Allow build & check packages in addition to changed templates

[tornaria]

To use, add "[ci check pkg1 pkg2 ...]" in PR title or body.

The idea is that sometimes I change some package but I want to test if another package (depending on the changed package) builds and checks ok (example #47610, or when updating ipython / cython / etc try build&check sagemath to see everything is fine, etc).

The implementation is just passing the pr title and body in the environment and have changed_templates.sh scan these for "[ci check ...]"

i feel like this kind of testing is better suited to local building. tools like ymir and xxbuild can be used to automate building multiple packages in one go

All testing can be done locally, so why have CI at all then?

seems like there is a lack of maintainer interest in this
