Update Cabal submodule to fix Windows builds
The Cabal submodule has been updated to a version that has an incorrect fix for autoconf.
The given version sets PATH_SEPARATOR to ;
forcibly which breaks use of older autoconf. This was fixed in https://github.com/haskell/cabal/pull/7652/files and released in Cabal 3.6.2.0
.
It's also very important not to release a toolchain with Cabal 3.6.1.0
.
Could the submodule be updated to this please.
