Make tests work with Python 3.13

[befeleme]

Attribute created of LogRecord is time.time_ns since Python 3.13: https://docs.python.org/3.13/library/logging.html#logrecord-attributes

This is not a backwards compatible change.

Would keeping both decorators make it compatible?

[befeleme]

It seems so, I updated the PR.

Hi @befeleme, @hroncok,

Just so you're aware it looks like python-json-logger is currently unmaintained, that said I am working on a maintained fork which includes testing against Python 3.13.

FWIW I don't see this test in your fork.

FWIW I don't see this test in your fork.

The test on the timestamp does still exist, however I've moved to using freezegun over unittest.mock.
