Force production docs to deploy on each push to main

[rezrah]

https://primer.style/css/ is not showing the expected production deployment.

This is because GitHub Pages resets the production environment on each push to main, which happens outside of our control

This PR will fix this by ensuring that all pushes to main branch deploy the docs each time, by removing the the file/folder pattern matching.
