Config inspector fails to load with `eslint-plugin-mdx`

[Simek]

Description

Attempting to run npx eslint --inspect-config in project using eslint-plugin-mdx results in the following error:

Failed to load eslint.config.js
Error: Could not find ESLint Linter in require cache
    at file:///W:/GitHub/react-native-website/node_modules/eslint-plugin-mdx/lib/processors/options.js:5:11

The check for require cache in the plugin seems to be a problem:

• https://github.com/mdx-js/eslint-mdx/blob/master/packages/eslint-plugin-mdx/src/processors/options.ts#L14-L22

The failure since to be OS agnostic (not related to paths), since it happens on macOS and Windows.

Reproduction steps

1. Check out https://github.com/facebook/react-native-website.
2. Run npx eslint --inspect-config at thge root to see the failure.
3. Comment out eslint-plugin-mdx import and its usages in eslint.config.js:

   import * as eslintPluginMdx from 'eslint-plugin-mdx';
   
   [...]
   
   ...eslintPluginMdx.flat,
   processor: eslintPluginMdx.createRemarkProcessor({
     lintCodeBlocks: false,
     remarkConfigPath: 'website/.remarkrc.mjs',
   }),

4. Re-run npx eslint --inspect-config, it should work now.

Don't know if anything we can do here. Seems it should be workarounded on the MDX plugin side.
