chore(storage): Update move logic now to support non-HNS buckets

[shubhangi-google]

This pull request broadens the utility of the move_file operation within the Google Cloud Storage Ruby client library. By removing the prior limitation to Hierarchical Namespace (HNS) enabled buckets, the move_file method can now be used with any bucket type, making the storage client more versatile and user-friendly for file management tasks.

Highlights

• Expanded move_file functionality: The move_file operation in the Google Cloud Storage client library now supports all bucket types, removing the previous restriction to only Hierarchical Namespace (HNS) enabled buckets.
• Documentation Update: The documentation for the move_file method has been updated to reflect its broader applicability across all bucket types.
• Enhanced Acceptance Tests: New acceptance tests have been added and existing ones modified to validate the move_file functionality on standard buckets, including tests for successful file movement and proper error handling when source and destination filenames are identical.

@shubhangi-google could you check why presubmits are failing.

hi @cpriti-os I am not facing this error when I am running the samples with my user this seems to be a permission issue with the user used by kokoro

@shubhangi-google AFAIK Move API is only supported for HNS buckets, for Non-HNS we will have to use copy + delete, correct me if I missed something. If not, could you add that and lets see if we still see move permission missing issue in this PR.

hi @cpriti-os this was the case earlier when move object API was supported by HNS bucekt only (#29391)
purpose of current PR is to provide support of move object- API to both HNS and NON HNS buckets
