Move angular-workspace to packages folder

[rajsite]

Pull Request

🤨 Rationale

Moves /angular-workspace to /packages/angular-workspace and also shrinks paths within the workspace:

• Moves /projects/ni/nimble-angular to /nimble-angular
• Moves /projects/ni/spright-angular to /spright-angular
• Moves /projects/example-client-app to /example-client-app

part of #2084

👩‍💻 Implementation

Straightforward move and path updates. No refactors / other changes.
Marked change as patch to verify publish infra.

🧪 Testing

• Manually opened all the ng-package.json to verify VSCode detects the schema paths
• Rely on CI for the rest

✅ Checklist

• I have updated the project documentation to reflect my changes or determined no changes are needed.

Looks good, once builds finish let's bypass any remaining owners policies to get this in before any conflicts arise.
