CI: Update workflows to use latest versions of the actions

[vt-alt]

This should quiet the warning:

The following actions uses node12 which is deprecated and will be forced to run on node16: actions/checkout@v2. For more info: https://github.blog/changelog/2023-06-13-github-actions-all-actions-will-run-on-node16-instead-of-node12-by-default/

Hmm, openSUSE builds also got broken (missing awk and git in their runs). perhaps this is unrelated to actions update and related to some docker image update since previous successful docker build was long 3 weeks ago. I will try add commit with a fix later to this PR.

Thank you, @vt-alt! I assume this is not to be merged yet?

I filed issue into GH checkout/action but they did not reply. This mean we will be not able to retain opensuse/leap for tests. If you are OK with it, I will add commit deleting it.

opensuse/tumbleweed fixes if we add gawk to zypper install.

ps. I said before 'it misses git' but I was incorrectly identified problem att.

I would be OK with it if there were a better reason to do it, but removing a currently working test just to silence a warning does not feel like a good tradeoff. Do I understand this correctly? What do you think?

[vt-alt]

Them we shall not merge it and postpone this until tests really fail with v1.

Perhaps they started to use tar from inside of contained in @v3, and leap image does not have it (but tumbleweed have it). So if I install tar and gzip (and reorder steps) build starting to work again. I reopen, and will push fixed version later today.

[vt-alt]

Can be merged now I think.
