Advanced user's documentation on VS Code is outdated

@reister It would be cool if you could update the advanced user's documentation on VS Code: https://git.h2t.iar.kit.edu/sw/armarx/meta/axii/-/tree/main/docs/advanced_users#vs-code

It can now be as concise as for QtCreator. I would do it, but I am not sure what is still important and what is obsolete now.

But I can prepare a draft if I come to it.
