This PR brings a couple of changes; - Removes undeed dependencies in bazel targets such as `//packages/common` & `//packages/core` - Removes RxJs usage - Adds `document-register-element` to architect test targets - Use @schematics/angular helpers - Uses the standard `$source": "projectName"` to get the projectName, which is defined in the `schema.json` - Use workspace writer to update the workspace config PR Close #33723
