[Bug] plugins of Pulsar clients for skywalking

### Search before asking

- [X] I searched in the [issues](https://github.com/apache/pulsar/issues) and found nothing similar.

### Version

OS: k8s pod
Pulsar version:
broker:2.10.2
pulsar-client:3.0.0

### Minimal reproduce step

I use pulsar，set consumer config。add negativeAckRedeliveryDelay、deadLetterPolicy params，like this:

```java
consumer = pulsarClient.newConsumer(Schema.STRING)
.consumerName("order-payment")
.topic(TOPIC_PAYMENT)
.subscriptionName("order-payment-sub")
.subscriptionType(SubscriptionType.Shared)
.enableRetry(true)
.negativeAckRedeliveryDelay(30, TimeUnit.SECONDS)
.deadLetterPolicy(DeadLetterPolicy.builder()
.maxRedeliverCount(3)
.retryLetterTopic(RETRY_LETTER_TOPIC_PAYMENT)
.deadLetterTopic(DEAD_LETTER_TOPIC_PAYMENT)
.build())
.messageListener(orderConsumer)
.subscribe();
```

when send message,the error occur:

```
java.lang.ClassCastException: class java.lang.String cannot be cast to class org.apache.skywalking.apm.plugin.pulsar.common.MessageEnhanceRequiredInfo (java.lang.String is in module java.base of loader 'bootstrap'; org.apache.skywalking.apm.plugin.pulsar.common.MessageEnhanceRequiredInfo is in unnamed module of loader org.apache.skywalking.apm.agent.core.plugin.loader.AgentClassLoader @2e4262d2)
at org.apache.skywalking.apm.plugin.pulsar.common.PulsarConsumerListenerInterceptor.lambda$afterMethod$cf935be7$1(PulsarConsumerListenerInterceptor.java:60)
at org.apache.pulsar.client.impl.ConsumerBase.callMessageListener(ConsumerBase.java:1147)
```

### What did you expect to see?

there is no errors，consumer can consume message normally。

### What did you see instead?

the error appearance:

```
java.lang.ClassCastException: class java.lang.String cannot be cast to class org.apache.skywalking.apm.plugin.pulsar.common.MessageEnhanceRequiredInfo (java.lang.String is in module java.base of loader 'bootstrap'; org.apache.skywalking.apm.plugin.pulsar.common.MessageEnhanceRequiredInfo is in unnamed module of loader org.apache.skywalking.apm.agent.core.plugin.loader.AgentClassLoader @2e4262d2)

```

### Anything else?

_No response_

### Are you willing to submit a PR?

- [ ] I'm willing to submit a PR!

Start at PulsarConsumerListenerInterceptor.java line 60 and trace the callback from ConsumerBase.callMessageListener in the reported consumer configuration. Reproduce with negativeAckRedeliveryDelay and deadLetterPolicy enabled, then verify that the consumer processes messages without the reported ClassCastException.
