PasswordAuth not disabled

[daef]

docker-entrypoint.sh:10 tries to disable password authentication, but fails because sshd_config contains whitespace+ between # and P

allowing for optional spaces fixes this:

sed -i "s/#\s*PasswordAuthentication yes/PasswordAuthentication no/g" /etc/ssh/sshd_config
