This reverts commit d2bc2683.

That seemed to break building on windows, before it starts building
git-annex at all, it tried to install ghc and something blew up:

Processing archive: C:\Users\runneradmin\AppData\Local\Programs\stack\x86_64-windows\ghc-9.0.2.tar.xz
Extracting  ghc-9.0.2.tar

Hopefully a newer ghc version or updated stackage version will fix this
at some point, in the meantime revert it.
