[CI] use ubuntu 22 for checkstyle/protobuf job

[pjfanning]

Subjob is failing in today's builds - make tool issues when running protobuf bits.

GitHub CI recently moved to unbuntu 24 for 'latest' install.

@cgivre the Splunk tests are failing and I don't think the PR changes here are the cause.

Splunk is such a steaming pile of great software.

@pjfanning I got 2 of the 3 failed test runs to pass simply by re-running. I'm not sure why but the Splunk tests are super flaky. We might just want to disable them on GitHub and run them manually before we cut a release.

@jnturton Do you have any thoughts on this?

[pjfanning]

I created https://issues.apache.org/jira/browse/DRILL-8516 to investigate why the make job fails on ubuntu 24.

Would it be ok to merge this as is - it gets the CI task to pass again and DRILL-8516 can be done later?

LGTM +1
Thanks for this.
