feat(plugin-twoslash): Make it possible to configure compilerOptions for TypeScript in twoslash

[Karibash]

Summary

Added compilerOptions option to @rspress/plugin-twoslash to allow customization of TypeScript compiler options used by Twoslash.
When displaying type information in code blocks with Twoslash, there are cases where you want to apply project-specific TypeScript compiler options. This feature allows you to flexibly customize the TypeScript environment used in code blocks within documentation.

Usage Example

import { defineConfig } from '@rspress/core';
import { pluginTwoslash } from '@rspress/plugin-twoslash';
import { JsxEmit } from 'typescript';

export default defineConfig({
  plugins: [
    pluginTwoslash({
      compilerOptions: {
        jsx: JsxEmit.ReactJSX
      },
    }),
  ],
});
