Test building all the publishable wheels on cibuildwheel updates

[webknjaz]

I realized that auto-merging dependabot bumps of $sbj like #1185 relies on building a small subset of wheels. However, this is an important bit of infrastructure that might manifest incompatibilities during release, too late in the process.
We should modify the workflow to also build all the wheels when this action is updated in dependabot PRs.

we can just let cibuildwheel run tests after it build wheel

https://cibuildwheel.pypa.io/en/stable/options/#testing

A way to do this may be, run tests with cibuildwheel, and a seprated job for cpython/pypy to run pure python version or yarl.

This will make ci simpler.

@trim21 those are already integrated but excluded in some cases due to being very slow in some envs like emulated QEMU and alpine. More things run in the release pipeline, but not on PRs.
Honestly, I did not expect anyone else to look into it as I was planning to do some thinking myself regarding how I want this shaped, keeping the broader cross-project context in mind. I'm not lacking knowledge regarding how cibuildwheel works, being a member of the PyPA myself.
Thanks for your input, though.
