Document legacy camera support in Bullseye #32
Description
It appears the latest bullseye adds legacy camera support back in. See https://downloads.raspberrypi.org/raspios_armhf/release_notes.txt This requires setup with raspi-config. So we need to test that this works, then update the docs.
- point to latests bullseye download in the Flash Operating System docs
- add any necessary documentation describing how to do the raspi-config steps to enable legacy camera support.
