Remove re-tagging of old Supervisor for unsupported architectures (#6679)

In #6347 we dropped the build for deprecated architectures and started
re-tagging of Supervisor 2025.11.5 images to make them available through
the tag of the latest version. This was to provide some interim period
of graceful handling of updates for devices which were not online at the
time when Supervisor dropped support for these architectures. As the
support was dropped almost 4 months ago already, the majority of users
should have hopefully migrated. The rest will now see Supervisor failing
to update with no message about architecture drop if they update from a
too old version. Since the re-tagged version also reported a failure to
update, the impact isn't so bad.
