fix docs and clean up finish release

[savente93]

Issue addressed

Fixes #1071

Explanation

the pixi command was outdated (html is now docs) so I removed that.

Aside from that I also think the docs version hasn't been detected correctly for a bit, leading to previous docs disappearing with some more explicit bash this should be at least noticed sooner I think. I'll revert previous versions soon

merging this without a review because the relevant parts can only be tested when merging a PR and everyone has gone home for the day. It's a fairly trivial change so it should be fine
