Has ghc-9.0 for windows changed to require installation?

[Takenobu Tani]

Hi devs,

The ghc-binary for windows needs to `make install` since ghc-9.0 [1].
Is this an intended change?

Previously, ghc-8.10.4 binary for windows [2] doesn't need to `make install`.
We only expand the tar-file and then we can execute `bin/ghcii.sh`.
