Change github.event.ref to github.ref

[kjelljorner]

According to the documentation, the variable GITHUB_REF which is accessed here via github.ref has the value refs/tags/<tag_name> for tags. github.event.ref just contains <tag_name> (as described here).

An alternative edit is of course

if: github.event_name == 'push' && startsWith(github.event.ref, 'v')

No problem, keep up the good work with cibuildwheel, it helps me a lot 😄
