ci: run on ubuntu-latest

[muzarski]

Pre-review checklist

• I have split my patch into logically separate commits.
• All commit messages clearly explain what they change and why.
• PR description sums up the changes and reasons why they should be introduced.
• I have implemented Rust unit tests for the features/changes introduced.
• I have enabled appropriate tests in .github/workflows/build.yml in gtest_filter.
• I have enabled appropriate tests in .github/workflows/cassandra.yml in gtest_filter.

I still need to figure out the following error:

Package libssl1.1 is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'libssl1.1' has no installation candidate

@dkropachev The ccm error still appears on ubuntu-latest:

Error starting node node1: unable to connect to scylla-jmx port 127.0.0.1:7199

What's interesting is it only appeared for older Scylla versions (OSS-RELEASE and ENTERPRISE-RELEASE passed without any issues). This error was the main reason why we rolled back to 22.04 in CI. Any ideas?

I am closing this one for now.
