[dark12345678]

Describe the bug
A clear and concise description of what the bug is.
this issue happened when i run the azure-spring-cloud-starter-eventhubs-kafka example which one in the sdk in china region, the tenant id is working when i run the keyvault example, so i am not sure why not working in the eventhubs kafka side. as i think the different is the keyvault can set the azure.keyvault.authority-host: https://login.partner.microsoftonline.cn and i haven't found any info for this in the AzureEnvironment properities.

kafka example
application yml file parts:
client-id: cccc (this is sp role which has added to the namespace IAM role assignment as Contributor role, has full access)
subscription-id: ccccc
client-secret: ccccc
tenant-id: ccccc
resource-group: cccc
environment: AzureChina
region: China North 2
eventhub:
namespace: cccc
