Automatically build when bluefin/common builds

[inffy]

Need to setup renovate(?) to monitor projectbluefin/common to automatically build after bluefin/common builds.

I think we should do this, but no automerge and a careful review of the changes so we don't end up rebuilding and publishing aurora just because bluefin merged a typo fix for something that doesn't even affect us.

What we probably should look into is to use tools like diffoscope to determine if the updates are actually important to us (shared directory) and/or to make reviewing of bump PRs easier as you can see a file per file difference.
