What does this PR do?

1. We released spring-cloud CLI extension 3.1.0 with below PRs:
   • Vendor AppPlatform 2022-03-01-preview SDK
   • Add support for AppMSI
2. Later we find this CLI extension is not compatible with Azure CLI version 2.26.0, the error is "No module named 'azure.core.rest'", see below screenshot.
   • 
3. Impact: all customers use old version of CLI and spring-cloud cli extension 3.1.0 will be failed to execute any spring-cloud commands.
4. Based on that most of the testing spring-cloud extension 3.1.0 is carried out with CLI 2.34.1, we update minimal requirement for azure-cli from 2.25.0 to 2.34.1 to quick mitigate this problem.
5. Release a new version of CLI 3.1.1 as fix.
