Subject: [PATCH] fix: make LoggerProtocol compatible with logging.Logger

Remove the positional-only marker (/) from LoggerProtocol.log().
logging.Logger.log() defines msg as a regular parameter, so the
positional-only constraint caused mypy to reject logging.Logger
as incompatible with the protocol.

Closes #554
