Example rate limit queue article gives a type error with latest wrangler typegen

### Existing documentation URL(s)

### What changes are you suggesting?

If you follow this guide now you'll get a type error on the queue consumer function

`Type '(batch: MessageBatch, env: Env) => Promise' is not assignable to type 'ExportedHandlerQueueHandler'.
Types of parameters 'batch' and 'batch' are incompatible.
Type 'MessageBatch' is not assignable to type 'MessageBatch'.
Type 'unknown' is not assignable to type 'Message'.`

### Additional information

I couldn't find any clear explanation of how to get type checking to work for queue messages easily.
