fix(logger): child logger must respect log level

[leandrodamascena]

Issue number: #5949

Summary

Changes

This PR addresses an issue where child loggers are unable to set different log levels from their parent loggers.

Currently, when creating a child logger using Powertools, the log level set for the child logger is not respected. This limits the ability to have different parts of an application log at different levels of verbosity.

Changes

• Modified the Logger class initialization to check if it's a child logger
• If it's a child logger, set the log level as specified in the constructor
• Add tests

Example

from aws_lambda_powertools import Logger

parent_logger = Logger(service="payment", level="INFO")
child_logger = Logger(service="payment", child=True, level="DEBUG")

parent_logger.debug("This won't be logged")  # Won't be logged (INFO level)
child_logger.debug("This will be logged")    # Will be logged (DEBUG level)

Backwards Compatibility

This change is backwards compatible. Existing code using Powertools loggers will continue to work as before, with the added benefit of respecting log levels for child loggers when explicitly set.
