Revert "lts-19.13 (ghc 9.0.2)"

This reverts commit d2bc268317.

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
...
Extracted total of 11790 files from ghc-9.0.2.tar
C:\Users\runneradmin\AppData\Local\Programs\stack\x86_64-windows\ghc-9.0.2-tmp-6d0fbe7f3b29e56c\ghc-9.0.2\: renameDirectory:pathIsDirectory:CreateFile "\\\\?\\C:\\Users\\runneradmin\\AppData\\Local\\Programs\\stack\\x86_64-windows\\ghc-9.0.2-tmp-6d0fbe7f3b29e56c\\ghc-9.0.2\\": does not exist (The system cannot find the file specified.)

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