Windows: cabal-3.0/2/?: symlinking feature not available

It seems that for older cabal versions the default install-method should be set to copy in the cabal configuration file.

I am seeing CI failures in the haskell setup action when switiching from choco to ghcup:

• use ghcup on windows (clone of #192) actions#206

• cabal-3.2.0.0: https://github.com/haskell/actions/actions/runs/4424951401/jobs/7759404053#step:8:28

  Symlinking 'hello-haskell-setup.exe'
  cabal-3.2.0.0.exe: Symlinking feature not available on Windows

• cabal-3.0.0.0: https://github.com/haskell/actions/actions/runs/4424951401/jobs/7759405410#step:8:16

  Symlinking 'hello-haskell-setup.exe'
  cabal-3.0.0.0.exe: Symlinking feature not available on Windows

GHCup doesn't manage your cabal configuration. The only exception is where we have to deal with msys2.

Ok, so then this has to be handled downstream by the setup action.
