Fallback to ghcup on windows (#206)

If choco installation fails, ghcup will now be tried on Windows. Also: looks for pre-installed GHCs by trying to `set` them through `ghcup`. Some commit headings that went into the squash: * Use ghcup from PATH on windows * Detect failure of `ghcup set` in isInstalled * Ensure cabal `install-method: copy` on Windows --------- Co-authored-by: Zubin Duggal <zubin.duggal@gmail.com> Co-authored-by: Finley McIlwaine <finleymcilwaine@gmail.com>
