chore: flatten dist directory and follow ESLint conventions

Prerequisites checklist

• I have read the contributing guidelines.

What is the purpose of this pull request?

In this PR, I've flattened the build output by moving files from dist/esm into dist and followed the ESLint convention of using defineConfig.

The primary reason for moving the build output to dist is to align with conventions used by other plugins such as CSS and JSON. In eslint/json#197 and eslint/css#352, I moved their build outputs from dist/esm to dist, since there's no longer a reason to support dual CommonJS/ESM packages going forward.

Also, I applied the previously missing defineConfig helper across the repository.
