Add a new ignorelist for mismatch between OBS and git

Sometimes, we need to backport a package version to a previous Apertis release. But, a fast-forward backport is not always possible as some changes may have occurred that are not suitable for previous Apertis releases (like a change in debian/apertis/component or debian/apertis/copyright needs to be refreshed with a different version or the toolchain). In order to keep the git history linear, while doing the backport, unsuitable changes are reverted and a suffix like "~v2023" is used for versioning.

Because this unsual workflow is a bit tricky, it's not possible to teach the dashboard about this suffix which makes it complaning for Mismatch between OBS XXX~v2023 and Git XXX.
