[cmd/builder] Improve TestVersioning (#10000)

<!--Ex. Fixing a bug - Describe the bug and how this fixes the issue.
Ex. Adding a feature - Explain what this achieves.-->
#### Description

Improves `TestVersioning` added on #9897.

The configurations were not what one would usually find, since when
running the builder we do some validation and setup.
This makes it closer to the real case.

In the process I removed the 'invalid' cases, since these error out
today already
