Use ubuntu-latest runner where possible

[antonwolfy]

This PR updates existing GitHub workflows to switch to use ubuntu-latest runner instead of ubuntu-22.04 one where it's possible.

Note, cron-run-tests.yaml still assumes to run tests on both ubuntu-22.04 and ubuntu-24.04 to validate both deployment paths.
And conda-package.yml still builds on ubuntu-22.04 to support running tests on any Ubuntu since 22.04.
