Remove old staging workflow and organize remaining ones (#5445)

I imagine we'll update the deploy to use Cloud Build eventually as well,
but I'd like to get some of this standardization in first to prevent
duplicate work (and comments).

This PR removes the old staging workflow and creates a new job to build
the site and check the links.

It separates the deploy job to a separate file as well, since it only
runs on push and will likely be replaced soon :)
