We need to update two locations to include support for `_oldest_unsynced_time` in the SSF replicators - https://gitlab.com/gitlab-org/gitlab/-/work_items/591313+ added scripts to automatically generate the boilerplate code for a new Geo Blob replicable. The scripts should be updated to include the base code for the oldest_unsynced_time metric on the new object - For Repository replicators, we should update the issue template `.gitlab/issue_templates/Geo Replicate a new Git repository type.md`.
