[BUG] 'authority' should be in Uri format when running in Docker container

Describe the bug When running below snippet in 3.1 .net core SDK container: creds = await ApplicationTokenProvider.LoginSilentAsync(_domain, _clientId, _clientSecret, adSettings);

When running on the host - no issues. Container has access to network with no limits.

To Reproduce Create a snippet that is creating creds Push code to container

Code Snippet creds = await ApplicationTokenProvider.LoginSilentAsync(_domain, _clientId, _clientSecret, adSettings);

Expected behavior shall return creds handler
