feat(ops/besadii): Make branch key cl/XXXX r/3303

The branch key for buildkite builds isn't actually used to fetch if a
commit is given - instead, it's just a visual grouping of multiple
builds. This means we can just make the branch key cl/<cl number>, which
is the convention we already use to refer to CLs and gets us a nice
visual grouping of builds of successive patchsets of the same CL number,
even though the ref we're providing isn't a real ref.
