Docs: Fix incorrect relative links

[kylegach]

What I did

1. Fix incorrect relative links
   • On a page inside a new directory (e.g. get-started/frameworks), almost* every relative link that went up a level (e.g. ../writing-stories/args.mdx) now needs to go up two levels (e.g. ../../writing-stories/args.mdx).
     • * The exception is relative links pointing to directories that are siblings of the current directory, e.g. on configure/integration, a link to ../user-interface/sidebar.mdx does not need adjusted.
2. Fix links that were missing new directories
   • e.g. ./api/main-config-typescript.mdx -> ./api/main-config/main-config-typescript.mdx
3. Replace remaining *.md docs links with *.mdx
