Subject: [PATCH] Only run push CI on pushes to main

Workflows were triggered for every branch, including those pushed into
forks (such as the tons of temporary branches on my fork),
meaning each fork of Pillow with Actions enabled was running a whole lot
of stuff for no great reason, burning resources for everyone.

This restricts the push trigger to `main` only.
If you want to run CI on your own fork, you can open a pull request
or use the workflow_dispatch trigger.
