Likely, I broke it in #4110

But it proves that the test now works

We need to bump the recommended version in the vanilla ghcup metadata.

Generally, recommended and latest are supposed to point to the same version. At least that's how it had been maintained before. If GHC devs want to deviate, I don't really mind, though.

This issue has been fixed, but we have a new one: https://github.com/haskell/haskell-language-server/actions/runs/8516412965/job/23326024633

closing this, but I will open a new issue.
