fix(kubevirt): use valid container image tags for vm create

The 'latest' tag for several containerdisk images was either missing or
not the most appropriate tag to use. This change updates the image
references to specific, valid tags to ensure reliability.

- 'ubuntu' is updated from 'latest' to '24.04'.
- 'centos-stream' is updated from 'latest' to '9-latest'.
- 'opensuse-tumbleweed' is updated from 'latest' to '1.0.0'.
- 'opensuse-leap' is updated from 'latest' to '15.6'.
