Address PR feedback: revert formatting and improve test

- Reverted formatting change in ResourceBuilderExtensions.cs (return statement on one line)
- Improved CommandLineArgsCallbackContextHasCorrectExecutionContextDuringPublish test to:
  - Remove unnecessary IsRunMode check in callback
  - Capture ExecutionContext to verify it's set correctly
  - Assert ExecutionContext is not null and in Publish mode
