Ok so this takes us back to #7123?

LGTM, I don't remember how many tests were failing when Zingo described it, glad to see only one :)

[digantdesai]

Can you comment why or a TODO(#TASK)? 🙏

It's a bit in a flux, both we and vela have not yet limited delegation to only support what the hardware, vela team adds/change some support/check now and then under regor development so it changes little per version. We currently handle this with skip/expected fail and have an internal task to clean it up when regor is more stable an we also have our config system in place.

I tried to diff the two version of vela to see what could cause the CI to break so we can more easy avoid this in the future. Unfortunately I could not find anything suspicious. All changes that was not in source files seem to not touch any version or dependency what I could detect.
