fix: Remove Bazzite info (DNM until next Bazzite release) (#662)

Do not merge this until this release is ready: ublue-os/bazzite#521

The Bazzite README is up to date with Discourse documentation, but the newest release still links the website for installation guide and FAQ, and even if it isn't in the best place right now, users will be confused if they click on something leading to a 404 page.
