SVN removed from GitHub ubuntu-latest causing build_release_candidate workflow failure

[Abacn]

What happened?

Found on 2.60.0RC2 build: https://github.com/apache/beam/actions/runs/11320467305/job/31478063174

Comparing

https://github.com/actions/runner-images/blob/main/images/ubuntu/Ubuntu2204-Readme.md

with

https://github.com/actions/runner-images/blob/main/images/ubuntu/Ubuntu2404-Readme.md (released 4 days ago)

SVN is removed.

Going to pin to ubuntu-22.04 for now to unblock release. Need to be fixed by the next release.

Move to P2 as currently mitigated. Still need to update the workflow to install svn in the future (in 2 year?)
