Use of datetime.utcfromtimestamp() on 3.12+ is also deprecated

[slothkong]

Hello there,

Although as of 1.7.0, deprecation of datetime.utcnow() was delt with by @RazerM ( 5273fa2 ), it seems like datetime.utcfromtimestamp() also requires some attention.

The official datetime docs point out:

Warning: Because naive datetime objects are treated by many datetime methods as local times, it is preferred to use aware datetimes to represent times in UTC. As such, the recommended way to create an object representing a specific timestamp in UTC is by calling datetime.fromtimestamp(timestamp, tz=timezone.utc).

For context, stumbled upon the deprecation warning while unittesting dbt-core, as part of issue 9791. When drilling down the logs, ended up at:

logbook/src/logbook/compat.py

Line 143 in e7cc074

return datetime.utcfromtimestamp(timestamp)

I put up a tiny pull request to address the deprecation warnings, hopefully as part of the next minor release 🤞

Any feedback is more than welcomed~
