Do not build wheels on push, since that is now accomplished by the re…

…lease job. (pantsbuild#19063)

Now that the release job is responsible for pushing SHAs to S3 (and
wheel building shards are only for _validation_ of the release process),
we no longer need to force building for `push` events, and can rely on
change detection.

This should significantly cut down on wheel builds.
