Che server pod fails to start if the Azure oauth config does not contain tenant id data

[vinokurig]

Describe the bug

We still support the Azure DevOps oauth until the existed oauth applications work, despite that creating new applications is not possible, see https://learn.microsoft.com/en-us/azure/devops/integrate/get-started/authentication/oauth?view=azure-devops#azure-devops-oauth-deprecated
If an Azure DevOps oauth is applied, che-server pod fails to start.

Che version

7.116@latest

Steps to reproduce

1. Apply an Azure DevOps oauth config
2. Go to the che-ser pod logs and see the error:

com.google.inject.CreationException: Unable to create injector, see the following errors:
