Option to flatten relative links for GitHub wikis

[coloursofnoise]

GitHub wikis flatten the folder structure which changes how relative links are handled:

To link to the file foo/file1.md from bar/file2.md, VSCode expects a link like ../foo/file1.md.
When the files are displayed in a GitHub wiki the folder structure is flattened so it expects just file1.md.

It would be nice to have the option to replicate this behaviour in VSCode to test links when editing wikis.

It appears Obsidian does the same thing if you make edits to a set of docs in it and save, so this might have extended use for that as well.
