[tor-relays] General overload -> DNS timeouts

To have the DNS trigger included in a shared trigger info
was a deliberate design decision as I understood it.

In my opinion it is better to remove this notice from Relay Search
for all affected versions, even if it will also remove the warning in
cases where the trigger was not DNS related, because
it potentially causes alarm fatique and operators will continue
to ignore the banner even after it got improved.

That is not easy for all of the operators that use the Torproject's Debian repos
since these versions are usually not "swiftly" available on deb.torproject.org yet
(unless you switch to nightly packages which I wouldn't recommend).
currently: Version: 0.4.6.8-1~d10.buster+1 [1]
