logging is disabled app-wide during fetching in quote.py

[Rogach]

Describe bug

Logging is disabled in the entire application while data fetching is happening in quote.py.

Here's the code responsible: https://github.com/ranaroussi/yfinance/blob/main/yfinance/scrapers/quote.py#L186
This change was introduced in 4e7b209, "Logging: improve appearance, fix propagation"

Perhaps it is possible to silence logging output only for certain loggers instead of all loggers at once?

Simple code that reproduces your problem

import logging
logging.basicConfig(level=logging.WARN)
logging.getLogger("modules").setLevel(logging.INFO)

import yfinance
def load_data():
    yfinance.Ticker("^HSI").fast_info.last_price
from threading import Thread
Thread(target=load_data, args=[], daemon=True).start()

logger = logging.getLogger("modules.Test")
logger.warning("TEST")

print("done")

Exprected output:

WARNING:modules.Test:TEST
done

Actual output:

done

Debug log

done

I remember wanting to silence everything during history calls in fast_info, particularly requests module. But I forget why. Given fast_info seems stable now, probably OK to revert.

I've tested without logging.disable, and the logs look okay - all at DEBUG level and mostly from yfinance itself.

Should I make a PR?
