Research direction

Start at src/installer.ts#L355 and inspect how the action resolves ghc_version: head. Compare the existing artifact URL with the proposed GHCup nightly channel and verify that the chosen approach can install the requested GHC version in the action; done means head or latest-nightly setup no longer fails with a 404.

Written by the indexing model from the issue text.

Description

Using ghc_version: head breaks; this URL is a 404:

https://github.com/haskell-actions/setup/blob/cc2e454616658fccc317c3cbd7a7f2c45c1d706c/src/installer.ts#L355

It would be great for one of the following to occur:

Fix the URL (e.g. https://gitlab.haskell.org/ghc/ghc/-/jobs/artifacts/master/raw/ghc-x86_64-linux-fedora33-release.tar.xz?job=x86_64-linux-fedora33-release)
Enable GHCup's nightly feature: https://discourse.haskell.org/t/ann-ghcup-0-1-19-3-released/6749

It seems like all that's needed for (2) is to upgrade GHCup installed by this action to 0.1.19.3 + set

ghc-version: latest-nightly
ghcup-release-channel: https://ghc.gitlab.haskell.org/ghcup-metadata/ghcup-nightlies-0.0.7.yaml
