bug#55024: [cuirass] '+' character in branch name causes problems

[Mathieu Othacehe]

Hello,

> https://ci.guix.gnu.org/jobset/wip-ipython%2Bpolyglossia.

Fixed in Cuirass with 1c45ae3c6b7ed9d99b2a1f61d707b40e68c2f7a4. The
commit is not yet deployed on Berlin but I took care of disabling the
wip-ipython%2Bpolyglossia specification in the database.

Thanks,

Mathieu
