Re-enable testing with specific kubernetes versions in subprojects

[maelvls]

We previously had the ability in open source subprojects to test with a given Kubernetes version, which would help with debugging or with checking the impact of a new feature.

It was mentioned in the open standup on 2024-07-16 that this no longer works (likely as part of the migration to makefile modules).

It would be good to re-enable testing with arbitrary kubernetes versions as we had before.

Do you know what broke this ability? Was the feature ever supported by makefile-modules?
