HLS 2.12.0.0 not working with GHC 9.12.2

[Raveline]

I have a ghcup with only the following installed:

• GHC 9.12.2
• Cabal 3.12.1.0
• HLS 2.12.0.0

GHC and Cabal work as expected. When running haskell-language-server-wrapper to check that everything is properly setup, I get:

GHC ABIs don't match!

I'll try to build hls from source to fix this, but in the meantime, it seems worth reporting that the installation from binaries don't seem to cooperate nicely.
