Trying to integrate with Coveralls using CircleCI, I am using the Coveralls Orb which uses this under the hood.

I have noticed the build numbers are really really long and take up far too much space. Doing a bit of digging around on the orb I see that it is the actual workflow id that is being sent and not the build number. I created a PR for the orb but realised I will also need this code updated too.
I see you don't accept PRs, so I am opening this ticket myself. But the lines to be changed are here.
Can these be updated so the display on the Coveralls UI would be nicer with a build number and not a UUID
