feature: update and simplify kickstarts

[tcooper]

This PR updates createhdds as follows...

• adds support for Rocky Linux 10,
• simplifies kickstarts to use $releasever and $basearch variables in the repository URLs,
• where required addition repositories are added to the kickstart to provide access to packages and/or environment groups not found or defined in BaseOS repository,
• minor updates to createhdds.py brought in from upstream.

All images have been regenerated to verify kickstarts...
