unixPB: CentOS Stream 10 updates and dockerfiles

[sxa]

CentOS Stream 10 is now available and this will be the basis of RHEL10 so it makes sense for us to be ahead of the game at run testing of Temurin on it.

Minor doc fixes are included in this too including updating the list of static docker hosts that we have which is well out of date (Maybe we should just remove the explicit list?)

Checklist

• commit message has one of the standard prefixes
• faq.md updated if appropriate
• other documentation is changed or added (if applicable)
• playbook changes run through VPC or QPC (if you have access)
• VPC/QPC not applicable for this PR
• for inventory.yml changes, bastillion/nagios/jenkins updated accordingly

Draft for now as we don't have a working replacement for Xvfb which is not in the repositories since CS10 has moved exclusively to Wayland.

Memo to self: Check applicability of #3945 to CS9/10

Noting that, curiously, the image created from the playbook updates does not have an openssl package so cannot perform builds unless BUILD_ARGS="--custom-cacerts false" prior to building.

Latest commits in this PR fixes this as it is the same thing that was causing the dev.functional test failures. openssh-server pulled in openssl on earlier versions, but not in EL10 so we now add it explicitly along with the other test tools.

New VPC run with F40 and C7: https://ci.adoptium.net/view/Tooling/job/VagrantPlaybookCheck/2100/
