Add firebaseio.com and firebaseio-demo.com to the HSTS preload list. (HSTS Preload History)

Commit Details

Commit Subject
Add firebaseio.com and firebaseio-demo.com to the HSTS preload list.
Commit Message
Both of these domains send a 422 status code at the root URL (they are meant to be accessed on subdomains), so the preload submissions site won't work, and I'm adding them in a separate commit.
