Get nushell by commit sha

[jacobmichels]

👋 thanks for building this!

It'd be great to not have to rely on fetching nushell via mutable tag. I'd much rather provide a commit sha instead. Is this something you'd be willing to accept a contribution for?

I wouldn't oppose this solution if it's sufficiently reliable and excellent, but I don't want to obtain nushell through compilation.

@jacobmichels Any update on this?
