CA Setup is incorrect in python:4-python3.11 Image (Sectigo CA)

[ytausch]

Steps to Reproduce

docker run -d mcr.microsoft.com/azure-functions/python:4-python3.11
docker exec -it <CONTAINER_NAME> /bin/bash
pip install requests
python
requests.get("https://www.uni-bayreuth.de/")

Output

requests.exceptions.SSLError: HTTPSConnectionPool(host='www.uni-bayreuth.de', port=443): Max retries exceeded with url: / (Caused by SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1006)')))

Expected Result

The request should go through normally.

It seems like there is an issue with the Sectigo CA that https://www.uni-bayreuth.de/ uses as other webpages don't cause trouble.
