docs(linter): Add configuration option docs for 5 rules.

[connorshea]

Part of #14743.

• typescript/no-namespace
• react/exhaustive-deps
• typescript/array-type
• promise/always-return
• eslint/curly

Generated docs:

## Configuration

This rule accepts a configuration object with the following properties:

### consistent

type: `boolean`

default: `false`

Whether to enforce consistent use of curly braces in if-else chains.


### curlyType

type: `"all" | "multi" | "multi-line" | "multi-or-nest"`

default: `"all"`

Which type of curly brace enforcement to use.

- `"all"`: require braces in all cases
- `"multi"`: require braces only for multi-statement blocks
- `"multi-line"`: require braces only for multi-line blocks
- `"multi-or-nest"`: require braces for multi-line blocks or when nested

## Configuration

This rule accepts a configuration object with the following properties:

### default

type: `"array" | "array-simple" | "generic"`

default: `"array"`

The array type expected for mutable cases.


### readonly

type: `"array" | "array-simple" | "generic"`

default: `null`

The array type expected for readonly cases. If omitted, the value for `default` will be used.

## Configuration

This rule accepts a configuration object with the following properties:

### ignoreAssignmentVariable

type: `string[]`

default: `["globalThis"]`

You can pass an `{ ignoreAssignmentVariable: [] }` as an option to this rule
with a list of variable names so that the last `then()` callback in a promise
chain does not warn if it does an assignment to a global variable. Default is
`["globalThis"]`.

\```javascript
/* eslint promise/always-return: ["error", { ignoreAssignmentVariable: ["globalThis"] }] */

// OK
promise.then((x) => {
globalThis = x
})

promise.then((x) => {
globalThis.x = x
})

// OK
promise.then((x) => {
globalThis.x.y = x
})

// NG
promise.then((x) => {
anyOtherVariable = x
})

// NG
promise.then((x) => {
anyOtherVariable.x = x
})

// NG
promise.then((x) => {
x()
})
\```


### ignoreLastCallback

type: `boolean`

default: `false`

You can pass an `{ ignoreLastCallback: true }` as an option to this rule so that
the last `then()` callback in a promise chain does not warn if it does not have
a `return`. Default is `false`.

\```javascript
// OK
promise.then((x) => {
console.log(x)
})
// OK
void promise.then((x) => {
console.log(x)
})
// OK
await promise.then((x) => {
console.log(x)
})

promise
// NG
.then((x) => {
console.log(x)
})
// OK
.then((x) => {
console.log(x)
})

// NG
const v = promise.then((x) => {
console.log(x)
})
// NG
const v = await promise.then((x) => {
console.log(x)
})
function foo() {
// NG
return promise.then((x) => {
console.log(x)
})
}
\```

## Configuration

This rule accepts a configuration object with the following properties:

### additionalHooks

type: `[
  string,
  null
]`

default: `null`

Optionally provide a regex of additional hooks to check.

## Configuration

This rule accepts a configuration object with the following properties:

### allowDeclarations

type: `boolean`

default: `false`

Whether to allow declare with custom TypeScript namespaces.

Examples of **incorrect** code for this rule when `{ "allowDeclarations": true }`
\```typescript
module foo {}
namespace foo {}
\```

Examples of **correct** code for this rule when `{ "allowDeclarations": true }`
\```typescript
declare module 'foo' {}
declare module foo {}
declare namespace foo {}

declare global {
namespace foo {}
}

declare module foo {
namespace foo {}
}
\```

Examples of **incorrect** code for this rule when `{ "allowDeclarations": false }`
\```typescript
module foo {}
namespace foo {}
declare module foo {}
declare namespace foo {}
\```

Examples of **correct** code for this rule when `{ "allowDeclarations": false }`
\```typescript
declare module 'foo' {}
\```


### allowDefinitionFiles

type: `boolean`

default: `true`

Examples of **incorrect** code for this rule when `{ "allowDefinitionFiles": true }`
\```typescript
// if outside a d.ts file
module foo {}
namespace foo {}

// if outside a d.ts file
module foo {}
namespace foo {}
declare module foo {}
declare namespace foo {}
\```

Examples of **correct** code for this rule when `{ "allowDefinitionFiles": true }`
\```typescript
declare module 'foo' {}
// anything inside a d.ts file
\```

Pull Request Overview

This PR refactors configuration schema handling for lint rules by moving configuration documentation from the declare_oxc_lint! macro into field-level doc comments on config structs. This enables automatic schema generation using serde and schemars, making configurations more maintainable and self-documenting.

Key changes:

• Added JsonSchema derive and serde attributes to config structs
• Moved configuration option documentation from macro comments to struct field doc comments
• Added config = ConfigType parameter to declare_oxc_lint! macro invocations
• Removed trailing whitespace from test strings in curly.rs
