This switches the android-components docker image to a debian 12 base,
although it could maybe stay on ubuntu 22.04 instead.
Since commit
ac9107b988,
application-services builds using an ubuntu 22.04 image, and android-components
consumes the nimbus-fml binary built from that, so running on debian 11 fails
due to an older libc.
Because pip in debian 12 refuses to work outside a virtualenv, pass
`--break-system-packages` to silence the error.
