feat: add a release workflow

[MangoIV]

Adds a new release workflow. This workflow adds a couple of things

• runs autoreconf and cabal sdist
• uploads the sdist as an artifact
• unpacks the sdist in another container
• runs configure script there
• uploads the configure log as artifact and as job summary (e.g. https://github.com/haskell/process/actions/runs/25102571704) for sanity checking
• documentation on how to use this information

[MangoIV]

Looks like github actions uploads are broken! yeyyyy

Not sure if this is ready for review, so can you request review when you want one? Thanks.

[MangoIV]

No, sorry, something is wrong with the action, I don’t know if it’s caused by gh or something I’m doing wrong. I’m gonna have a look. ^^

[MangoIV]

I think this would be ready for review, sorry for the long wait, @tomjaguarpaw

[tomjaguarpaw]

Thanks, this is great! The explanation of how to use it could benefit from a little elaboration and clarification. Happy to suggest some wording, but at the moment I don't know what it means.

@tomjaguarpaw is it okay if I add a .editorconfig in the root here as well while I'm on it? I think the consistency in the README and in the Haskell files would benefit from it.

https://editorconfig.org/ is supported by all editors and much less controversial than automatic formatting.

Let's do that in a separate PR.
