Autocompletion for `occ`

[joshtrichards]

See whether it's feasible to enable autocompletion for occ within the image: https://docs.nextcloud.com/server/latest/admin_manual/occ_command.html#enabling-autocompletion

There are some hurdles, such as needing bash-complete + the www-data profile/nologin usage
