Create proper source tarballs in CI/on releases

[hasufell]

Implementing https://gitlab.haskell.org/haskell/ghcup-hs/-/merge_requests/180 I need proper source tarballs.

The default ones are:

1. autogenerated and would depend on github not messing with the tarball layout (they did so at least twice) for the hash to be stable
2. depend on the tag (yeah, if you force push, the hash changes too)
3. have bad tarball names like 1.4.0.tar.gz, causing trouble for ghcup

Something like:

git archive --prefix=haskell-language-server-${version}/ --format=tar.gz -o haskell-language-server-${version}.tar.gz HEAD

in CI should do the trick.

@hasufell the mr is merged and released, how could improve it creating source tarballs here? are you using them from gitlab in the actual version?

[hasufell]

ghcup is using the source tarballs

ghcup is using the source tarballs

the default ones from github? so improving them would allow clean ghcup code

I don't understand what you mean. ghcup needs source tarballs to compile HLS from source. The automatically generated ones aren't good enough as I described in the first comment.

hmm so if default ones are not valid and we are not generating in github the good ones yet, Where are the tarballs it is using now from?

Created on my own.

thanks, will add a job in the build workflow to generate and add them to sha256 sums
