The issue seems to be glibc version=2.31 and debian11.

Kindly add back support for debian11.

I don't think CI worked:

There is no artifact that I can see. I think the renaming didn't work and they are overwritten. I'll have to give it another go.

Let's see if this is fixed with https://github.com/mavlink/MAVSDK/releases/tag/v2.12.2.
