fix: drop the redundant daily from the Zomboid logrotate config

logrotate warns that size overrides daily, and it is right: with both set the
time directive does nothing. The daily timer is when the config gets checked;
100M is when it rotates. Saying so in a comment rather than in a directive
that has no effect.
