Problems don't update when files are deleted

[Jantho1990]

When a file is deleted, any issues for that file that are listed under the Problems tab stay there until you restart VS Code.

The issue doesn't seems to come from the VSCode plugin itself.

When a file is deleted, the LSP doesn't republish the diagnostics. I assume the LSP doesn't detect these file deletion. Futher more, the LSP specification defines the creator of the diagnostics as their owner (see microsoft/language-server-protocol#463).

The issue cannot be fixed on the extension side as there is no way in the API to clear out diagnostics from VS Code itself.

Issue godotengine/godot#43133 open for resolving this issue on the LSP server.
