remove beta notice for queue-processor mode (#430)

 The aws-node-termination-handler **[Instance Metadata Service](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2-instance-metadata.html) Monitor** will run a small pod on each host to perform monitoring of IMDS paths like `/spot` or `/events` and react accordingly to drain and/or cordon the corresponding node.
 
-The aws-node-termination-handler **Queue Processor** will monitor an SQS queue of events from Amazon EventBridge for ASG lifecycle events, EC2 status change events, and Spot Interruption Termination Notice events. When NTH detects an instance is going down, we use the Kubernetes API to cordon the node to ensure no new work is scheduled there, then drain it, removing any existing work. The termination handler **Queue Processor** requires AWS IAM permissions to monitor and manage the SQS queue and to query the EC2 API. The queue processor mode is currently in a beta preview, but we'd love your feedback on it!
