README: document USB prep via GitHub ZIP download

The previous USB instructions assumed git was available. Added step-by-step
for the no-git path: GitHub ZIP download → unzip → copy to USB → run
bootstrap.sh. Includes the Ubuntu auto-mount path tip for finding the
drive name. Folder name note (ubuntu-post-install-main from ZIP) added.
