Fix s6 dependency by removing download-models

[Daniel-dev22]

Looks like this was missed in #10717

Leading to

s6-rc-compile: fatal: during dependency resolution for service frigate: undefined service name download-models
s6-rc: fatal: unable to take locks: No such file or directory
s6-linux-init-shutdownd: warning: /run/s6/basedir/scripts/rc.shutdown exited 111
s6-rc-compile: fatal: during dependency resolution for service frigate: undefined service name download-models
