Resolve "Geo: Replicate deletion of remote stored files"

What does this MR do and why?

Updates Geo::FileRegistryRemovalService to try removing a file from object storage if it cannot be found in local storage.

How to set up and validate locally

1. Setup a Geo instances using object storage replication
2. Currently, removing a file backed by object storage should result in the file remaining on the secondary object storage bucket, and the secondary sidekiq instance logging an error:

   Unable to unlink file because file path is unknown. A file may be orphaned

3. Upgrade to package from this MR
4. Removing a file backed by object storage should now remove the file from the secondary object storage bucket
5. Manually destroy file (for a package file for instance):
   1. Create a project with a package file in the package registry
   2. Find the model id by checking in the Geo event log for the created event
   3. In a rails console on the primary instance run:

      Packages::PackageFile.find(ID).destroy!

   4. Verify that object is removed from primary and secondary object storage
