 ### Adding a new GHC version

-1. open the latest `data/metadata/ghcup-<yaml-ver>.yaml`
-2. find the latest ghc version (in yaml tree e.g. `ghcupDownloads -> GHC -> 8.10.7`)
-3. copy-paste it
-4. adjust the version, tags, changelog, source url
-5. adjust the various bindist urls (make sure to also change the yaml anchors)

   The major changes here were switching `hpath` library out for `filepath`/`directory` (sadly) and
   introducing a non-unix way of handling processes via the `process` library. It also introduced considerable
