Release Note Description

[lbussell]

[Triage] @AndriySvyryd is this still needed? And is there any reason why this shouldn't be upgraded to Ubuntu 24.04 instead of 22.04?

Pinging @dotnet/dnceng who is the codeowner of this Dockerfile.

[AndriySvyryd]

Yes. And 24.04 would work as well

[SamMonoRT]

@richlander - any suggestions on how to proceed making this update?
