Use the service connection instead of PAT to kick off docs CI runs (Azure#29870)

The msdocs-apidrop-connection service connection will replace the
azuresdk-apidrop-devops-queue-build-pat that was being used to kick off
runs.

The docindex run was run against this refs/merge for both testing and
also initial approval of the service connection.
