More resilient publish workflow options

[jessedp]

This solves two challenges I faced when upgrading the publish workflow:

1. Without the signing environment vars setup in GH, the build breaks
   • I didn't test this, but I imagine defining them with incorrect values is also unhelpful
2. Building a "msi", "rpm", or "deb" under only MacOs caused build problems. Running each build on the native OS has so far allowed those to work.

This setup (with some other stuff) is running/working over here.

Thanks for this :)

A few questions:

Building a "msi", "rpm", or "deb" under only MacOs caused build problems.

what build problems did you run into?

It's possible that I was fighting publishing timeout problems.

Not sure if you can see the logs, but these are the runs from the branch I was testing on (DEBUG=electron-builder* is set).

If you can, here's one example that's not just a publish timeout.

I guess one additional benefit is that this also enables more parallel/"faster" builds.
