Automate regression updates
Created by: APJansen
Aim
Be able to add a red-regressions label and have the regressions be recomputed in the CI and automatically committed.
Status
It seems to be working for the extra regression tests, the result of the workflow applied to this PR as a test is the commit d142744
I don't know about the fitbot, if we want to automate that too I guess it would be a different workflow but using the same label. And what would need to be updated exactly? The developing_weights are a starting point, so I assume those stay the same. Would you want to update the reference fit that it compares against?
Also, I expected the bot's push to trigger the other tests again, but it seems this doesn't happen. I don't know if that's necessary or not.
