commit e9e0377f452e9d3f600011e0714cc6c779f10bab
from: Stefan Sperling <stsp@stsp.name>
date: Wed Mar 29 13:30:59 2023 UTC

avoid gitwrapper printing a warning when /etc/gotd.conf does not exist

gotd still requires the config file, of course, but gitwrapper must
treat is as optional and remain silent if the file cannot be found.
