Probably need a way to turn off the Mac + Enzyme combo which is known to be bad due to underpowered mac mini runners

I definitely agree that we should start using similar setups in many places, but it could be nice if we could uniformize this and use a shared action/test setup, to keep this maintainable in the future?

Sure. I set this up here because the Enzyme tests are impacting other people. If someone wants to set up the shared workflow now, I don't see a problem, otherwise we can do this now and then remove it in another PR later once the shared one is set up?
