Remove extended glob pattern from branch protection UI (#33125)

Underlying go library has no support for it

Fixes: #33121

---

I never touched frontend tests so pointers how to write them are
welcome.

This can be either fix or workaround, depending if this is something
gitea should support in the future or not. The golang side is unlikely
to get updates though.
