bean-price fetching issue with yahoo

[Vinit Khandagle]

I am seeing the below error while trying to fetch prices from yahoo, not sure how to solve this issues

bean-price -e "USD:yahoo/AAPL" --no-cache

```

File "/Users/vkbytes/miniforge3/lib/python3.9/site-packages/beanprice/sources/yahoo.py", line 129, in get_latest_price
    raise YahooError("%s (ticker: %s)" % (error, ticker)) from error
beanprice.sources.yahoo.YahooError: Status 401: {'code': 'Unauthorized', 'description': 'Invalid Cookie'} (ticker: AAPL)
```

I ran into the same thing a couple days ago. This fix worked for me:
