I see nothing for today when the error happens in /opt/mailman/var/logs/smtp.log
But the log has a bunch of these, but these stopped around the 4th

These are normal messages from the startup of Mailman's lmtp runner. If you correlate these with mailman.log, you'll probably see the server starting at these times.
The fact that there is nothing in this log correlating with the Postfix message
2021-08-06T09:08:41.974225-04:00 dockerhost postfix/lmtp[109783]: D630B3083ED0: to=<test@mailman-docker.###.####>, relay=localhost[127.0.0.1]:8024, delay=0.11, delays=0.05/0.02/0.04/0, dsn=4.4.2, status=deferred (lost connection with localhost[127.0.0.1] while receiving the initial server greeting)
seems to say that Postfix isn't really connecting to Mailman's lmtp and this is consistent with netstat -l not showing something listening on port 8024.
I note you have
lmtp_host: localhost
in the [mta] section in mailman-extra.cfg. Try changing that to
lmtp_host: 127.0.0.1
