vscode-proto3 support using the import protobuf files.

pbkit lsp supports buf workspace https://docs.buf.build/reference/workspaces#configuration
try creating a buf.work.yaml file

I tried using the pbkit lsp with buf and I can't seem to get it to support auto-completion or "Go To Definition" for imports. I tried looking for pbkit logs, but couldn't find anything meaningful.

Update: Got it to work by placing the buf.work.yaml at the root of the workspace.

It would be great if a buf.work.yaml wasn't strictly required (i.e. detect buf.yaml too) and it didn't have to be at the workspace root.

What doesn't work though is:

• auto-completion using a package prefix (e.g. foo.v1. ...)
• auto-completion of buf-imports deps
