Update to newer OS images for install testing

[dereknola]

Proposed Changes

Update the OS boxes used for install and E2E testing.

• Moved off generic publisher, as they suddenly stopped publishing boxes 7 months ago. The new box choices are stable, regularly updated images from known 3rd parties.
  • generic/ubuntu2204 and generic/ubuntu2310 ➡️ bento/ubuntu-24.04
  • generic/rocky8 ➡️ eurolinux-vagrant/rocky-8
  • generic/rocky9 ➡️ eurolinux-vagrant/rocky-9
  • generic/fedora38 ➡️ bento/fedora-latest (currently fedora40)
• Replaced centos7, which is EOL and the repo lists are now dead, with centos stream 9. While there has been a move away from centOS stream, it is still used enough for testing purposes. generic/centos-7 ➡️ eurolinux-vagrant/centos-stream-9
• Simplified E2E OS setup code to handle more generic versions of OSes

Further Comments

While I could have chosen more first party publishers, like the official rocky linux boxes, these are not actually updated regularly (rocky 8 is still on 8.9 despite 8.10 being published in May)
