docs(linter): Add autogen doc support for max_nested_describe in jest plugin.

[connorshea]

Related to #14743.

This results in the addition of a config block in the docs, like this:

## Configuration

This rule accepts a configuration object with the following properties:

### max

type: `integer`

default: `5`

Maximum allowed depth of nested describe calls.

There were also some extra linebreaks I removed from the declare_oxc_lint! call.
