stg rebase <ref> does not work when ref contains @

[lthms]

Hi everyone.

I updated to the lastest version today, and found a regression related to reference handling. As far as I can tell, git revisions are not recognized when they contain certain character. At $WORK we use @ in our branch names, for instance.

How to reproduce

git init
touch t
git add t
git commit -m "add t"
git branch lthms@reproduce
stg init
stg rebase lthms@reproduce

was working with 2.1.0, but does not work with 2.2.1.

As far as I can tell, the culprit is likely to be gix_revision::spec::parse. I’ll keep investigating.

Good news, I was able to check that GitoxideLabs/gitoxide#803 fixes the issue locally.
