* Use MD LS for resolving all document links
This switches the markdown extension to use the markdown language service when resolving the link. This lets us delete a lot of code that was duplicated between the extension and the LS
* Pick up new ls version
Fix markdown link diagnostics not updated when directories are renamed/deleted
Turns our that `createFileSystemWatcher` will not fire if a parent dir is renamed / deleted. See #60813
To fix this, I believe we have to create watchers for all parent directories too (or watch everything in the entire workspace)
* Add experimental support for update markdown links on file moves/renames
Fixes#148146
This adds a new experimental setting that automatically updates markdown
Note that this needs a new version of the vscode-markdown-languageservice so the build is expected to break for now
* Pick up new LS version
* Move MD diagnostics to language server
This switches us to using the LSP pull diagnostic model with a new version of the language service
* Bump package version
* Delete unused file
