Describe the Bug

Currently, we can supply the delivery_delay parameter under the [[queues.producers]] sections in the wrangler.toml/jsonc file. This is not expected behaviour as a worker should not be able to affect queue level settings. Additionally, when having multiple producers, the setting will be determined by the last deployed producer which also leads to issues.

Please provide any relevant error logs
