(post mvp) add mdx syntax support for comment parsing

[FroyaTheHen]

Research how the mdx syntax can be properly supported. Comment parsing for mdx would probably not work with pulldown_cmark. In that case, what is needed would be either: a separate interpreter for mdx syntax + a way for the comment parser to recognise which md/mdx syntax is used, or (imo better alternative but might be more time-consuming if on house solution) one that would support both without a need to distinct between mdx/md.

Note: consider throwing away the event parsing logic and see if that can work properly for all cases.

See possible solution: https://github.com/wooorm/markdown-rs?tab=readme-ov-file#extensions

ensure the new solution is compatible with the md, as this may change doc formatting for already existing packages
