[Submission Pipeline] Tasks for module deletion

[ruanxin]

Description

The current pipeline handles module sunset by executing deletion actions—specifically, it removes images from the registry and deletes modules from the repository. To maintain consistency, the new submission workflow must incorporate these same deletion steps.

Acceptance Criteria

• Add a step in new-submission-workflow.yaml to Delete image from registry.
• Add a step in new-submission-workflow.yaml to Delete module from repository.
• If the existing script decide-if-delete-from-gcr.sh, delete-repository.sh can't be reused, implement new script instead of enhancing existing.
