LSP - Understand npm workspaces #24505
Description
I believe the lsp doesn't understand npm workspaces at the moment.
- Need to implement this for the lsp too when not byonm: fix(workspace): support resolving bare specifiers to npm pkgs within a workspace #24611
When implementing this, I think we should get the lsp code using deno_config::workspace::Workspace:: discover so that we have a single implementation of workspace discovery.
