This PR fixes several things:

• First, the ASV jobs have been failing since #1495 because asv defaults to calling setup.py and wasn't calculating the version string correctly anymore. This affected both our "quick" CI check and the nightly VM job.
• Second, the "quick" CI check wasn't reporting those failures correctly to the github UI, so it showed up as a green check mark instead of a red X.
• Third, address @wholmgren's comment regarding the CI check for forks: https://github.com/pvlib/pvlib-python/pull/1454#discussion_r884026716
