Deprecated use of rsyslog options

[myOmikron]

When starting rsyslog, the following warning is produced:

May 23 20:05:36 mail rsyslogd[1377]: warning: ~ action is deprecated, consider using the 'stop' statement instead [v8.1901.0 try https://www.rsyslog.com/e/2307 ]

docs/post_installation/firststeps-logging.en.md:

# For Rsyslog only:
# To move local3 input to /var/log/mailcow.log and stop processing, create a file "/etc/rsyslog.d/docker.conf":

local3.*        /var/log/mailcow.logs
& ~

# Restart rsyslog afterwards.

Used OS: debian-10
rsyslog-version: Version: 8.1901.0-1+deb10u1
