93813a5079 logging/ascii/json: Make TS_MILLIS signed, add TS_MILLIS_UNSIGNED
It seems TS_MILLIS is specifically for Elasticsearch and starting with
Elasticsearch 8.2 epoch_millis does (again?) support negative epoch_millis,
so make Zeek produce that by default.

If this breaks a given deployment, they can switch Zeek back to TS_MILLIS_UNSIGNED.

Thanks for @timo-mue for reporting!

Closes #4494
