feat(linter): add auto-fix for vue/no-required-prop-with-default

[amondnet]

Summary

Add auto-fix capability to the vue/no-required-prop-with-default rule which detects props that have both required: true and a default value.

Fix Strategies

TypeScript props (withDefaults, defineProps):

• Insert ? after the property key to make it optional
• Example: name: string → name?: string

Options API props (defineComponent, export default):

• Replace required: true with required: false
• Example: required: true → required: false

Example

<!-- Before -->
<script setup lang="ts">
interface Props {
  name: string  // required but has default
}
const props = withDefaults(defineProps<Props>(), {
  name: "World"
});
</script>

<!-- After (with fix applied) -->
<script setup lang="ts">
interface Props {
  name?: string  // now optional
}
const props = withDefaults(defineProps<Props>(), {
  name: "World"
});
</script>

Test Plan

• All existing no_required_prop_with_default tests pass
• Added fix test cases for:
  • TypeScript interface props
  • TypeScript type literal props
  • Options API props with required: true
  • defineComponent props
  • Destructured defineProps
• Clippy passes without warnings (in our code)
• Code formatted with cargo fmt

This PR adds auto-fix capability to the vue/no-required-prop-with-default linter rule, which detects Vue props that incorrectly specify both required: true and a default value.

Key Changes:

• Implements two distinct fix strategies: inserting ? for TypeScript interface/type props, and replacing required: true with required: false for Options API props
• Changes rule status from pending to fix to enable auto-fix functionality
• Adds comprehensive fix test cases covering TypeScript interfaces, type literals, method signatures, Options API, and destructured props
