ci: for branches, use a single trigger
This trigger will unlock all the job necessary to build wheels and upload
nightly build. This should make the nightly build process more pratical.
In practice right now, only run pipeline for branch by creating them explicitly
on the web. So we could just run everything without trigger, but this is a
decision for later. This changeset only focus on making the nightly build
process somewhat manageable.
