Add tests for KeyManagementProvider refresh logic and certificate ver…

…sion validation

- Added a test to validate the refresher reconcile count with modified timing and Key Vault configuration.
- Implemented a test to ensure certificate version updates are correctly reflected in KeyManagementProvider after creating a new version in Azure Key Vault.
- Created a test to verify that a specified certificate version in KeyManagementProvider remains consistent after attempting to update the certificate in Azure Key Vault.
