Deleting & renaming

Once an action is successfully parsed, it becomes permanent in the workspace. When an action is removed, it changes it state to deprecated, but can still be added from the action list and continues to work in its host pipelines. This is a security measure to prevent pipelines from failing in case the action repository is unwillingly removed. Changing the name of the action in action.yml creates a new action in the workspace, leaving the old as it was.
