Add Wasp SDK to npm Workspaces #3233
Description
Based on #3159
The Wasp SDK is not currently added as a workspace to the user project.
If we did it, we could remove the specific npm install step from the SDK, and have even stronger dependency sharing.
The blocker is #2482, because when npm resolves the dependencies there's one deep in the tree that asks for @types/react@19 and we only have @types/react@18, so it errors out.
