Remove Workaround for US Gov Bug

[MarkDordoy]

Remove the workaround as the bug is now resolved. This was confirmed to me by Microsoft in a support ticket and I've also no longer been able to reproduce the issue using V1.0 of the API.

PR change reverses the use of the beta endpoint.

Original PR to fix bug can be found here #936

TFW you spend all your time on github enterprise, then "approve" a PR without realizing it's someone else's repo on github.com 🤣
