Installing Bluefin onto a Framework Laptop 13 AMD/Intel

Just a heads-up, the numbering here goes from 1 to 3 (skips 2). Also, it may be helpful to have a separate section for people who already have an atomic build and just want to rebase to the framework laptop image. The Bazzite installation page already provides such instruction, by the way, so for consistency it may be a good idea to do the same for Bazzite and Aurora.
