Bugfix to correct GCSHook being called even when not required with
BeamRunPythonPipelineOperator (#38716)
* Bugfix to correct GCSHook being called even when not required with
BeamRunPythonPipelineOperator
* remove unneccary check for GCSHook and add unit test for
BeamRunPythonPipelineOperator to ensure that GCSHook is only called when
necessary
* Split out unit tests for TestBeamRunPythonPipelineOperator with GCSHook
'gs://' arg prefixes
* Fix formatting
