remove unneeded TaskLogStreamer binding override

Fix log and report streaming for tasks run by the kubernetes task runner

#14040 added a binding from TaskLogStreamer to TaskLogs. This binding overrode the existing binding from TaskLogStreamer to SwitchingTaskLogStreamer in CliOverlord. The effect bing that calls to get task reports or logs in the overlord api would go directly to check task storage instead of checking the task runner first. Since the binding from TaskLogStreamer to TaskLogs is not needed, we remove it here.
