Microsoft Translator Https ConnectionError (Docker only?)

[Kyuuu]

Describe the bug

With the newest update via Docker (Weblate 4.1.1) in every language this popup appears:

Żądanie tłumaczenia maszynowego przy użyciu Microsoft Translator nie powiodło się: ConnectionError(MaxRetryError("HTTPSConnectionPool(host='westeurope.https', port=443): Max retries exceeded with url: //link.cognitiveservices.azure.com//sts/v1.0/issueToken?Subscription-Key=token (Caused by NewConnectionError('<urllib3.connection.HTTPSConnection object at 0x7ff1926c5048>: Failed to establish a new connection: [Errno -2] Name or service not known'))"))

Additional context
Google translate works fine:

Looks wrong, maybe wrong setting for MT_MICROSOFT_ENDPOINT_URL. You probably don't need this one unless you are in China.

This issue looks like a support question. We try to answer these reasonably fast, but in case you are looking for faster resolution, please consider purchasing support subscription and make Weblate stronger.

Our MT_MICROSOFT_ENDPOINT_URL starts with "https://" which is missing in the error message (it starts with //), which would result in "[Errno -2] Name or service not known" as the protocol is missing from URL.
Since it began with the latest docker update (and was working fine before) it seems that something changed in regard to reading that setting from settings-override.py

MT_MICROSOFT_ENDPOINT_URL should be just domain name.

This setting did not exist prior to 4.1, so maybe that's why it didn't cause anything. It was introduced by f95b8a5 via #3916
