Docs: Fix Environment Variables names in table for LOGGER

[kylez-ithaka]

What were you searching in the docs?

The documentation for logging references incorrect Environment Variable names in the reference table with definitions, but the rest of the documentation uses the correct values for the variable name

Is this related to an existing documentation section?

docs/core/logging.md

How can we improve?

Fix the names

Got a suggestion in mind?
