changed the description

The thing that is strange is that there is no warning about "buster" which is even older than bullseye.

The warning about buster was reported in an old bug report T10082, I guess there is an issue with the cache since the warning disappeared by itself.

Triggering a rebuild of the dashboard without using the cache file was enough to fix (temporarily) this issue. I saved a cache file triggering this issue for further analysis: packaging-cache.7z

added priority:normal label and removed priority:needs triage label

removed release:v2023 label

removed release:v2024 label

removed release:v2025pre label
