CI: Replace CentOS Stream 8 with Alma, Rocky, or Oracle Linux due to EOL

[AkihiroSuda]

CentOS tests seem failing

For CentOS stream 8, that may be expected; it's EOL since May 31 (just got hit by that in some CI pipeline that als had it in the Matrix)

I guess we now have to replace CentOS with Alma, Rocky, or Oracle Linux?

I guess we're fine with #4304 for now (PTAL). I'll ask around if we can get a free RHEL license (maybe even free compute resources) to test on.

To test on RHEL using Red Hat's infra, we need to setup https://github.com/marketplace/packit-as-a-service org-wide. @caniszczyk @amye can you help?

Google cloud has removed centos-8 stream now, it causes cirrus ci start failure: https://github.com/opencontainers/runc/pull/4299/checks?check_run_id=25802936493

Let's remove it for now. Once we'll get help from org maintainers (see above), I'll work on adding RHEL.

Alternative solutions are also welcome, of course.
