[devbox] Improve release process (#2556)

## Summary
Change release process workflow to support both "snapshot" releases (i.e. nightlies, manual development versions) and full releases (done by tagging a commit with a new version).

## How was it tested?
I'll test by running the workflow manually.

## Is this change backwards-compatible?
Yes.
