<:issue_open:882464248951877682> [litestar-org/litestar] Bug: Logs and Stack traces are not visible OOTB in Python3.12

# Description
Logging (on routes) and also stack trace (when using litestar.testing.create_test_client in debug mode) don't appear to be printed on the terminal when executed in Python 3.12. Running the minimal example in Python 3.8, I can see contents of the "Logs" section in my terminal; both a WARNING and an ERROR log, along with a stack trace. However, neither is visible when run on Python 3.12. There is one workaround (that I am aware of) shared by @cofin in the Discord server but (IMO) these functionalities should simply "just work".

@cofin's example modified to suit the example code (the actual MCVE is under the MCVE section)

import logging
from litestar import get, Request
from litestar.logging.config import LoggingConfig
from litestar.testing import create_test_client


@get()
async def evil_route(request: Request) -> str:
    request.logger.warning("you can't see me")
    1 / 0
    return "so, you will never catch me"


with create_test_client(
    [evil_route],
    logging_config=LoggingConfig(
        root={"level": logging.getLevelName(logging.INFO), "handlers": ["console"]},
        formatters={
            "standard": {
                "format": "%(asctime)s - %(name)s - %(levelname)s - %(message)s"
            }
        },
    ),
) as client:
    response = client.get("")
    assert response.status_code == 500

from litestar import get, Request
from litestar.testing import create_test_client

@get()
async def evil_route(request: Request) -> str:
    request.logger.warning("you can't see me")
    1 / 0
    return "so, you will never catch me"

with create_test_client([evil_route]) as client:
    response = client.get("")
    assert response.status_code == 500

1. Save as "some_python_file.py"
2. Run `python some_python_file.py`
4. See error (actually you can't :p that is the error)
