v5.0.1-preview0002

[v5.0.1-preview0002]

Fixed

• Fixed pipeline build step by limiting Gitversion to 5.* version.
• Change default integration test region from East US to Australia East due
  to quota limitations.
• Removed MacOS-11 testing from build pipeline because it is no longer supported
  by Microsoft managed Azure DevOps images.
• Changed integration tests to display the removal of the Cosmos DB account
  in the teardown phase to ensure the account is removed after the tests are
  completed.
