### Environment

* Dubbo version: 3.2.0
* Operating System version: macos10.15.7
* Java version: 1.8

### Steps to reproduce this issue

### Expected Behavior

set http2Disable default value into http2Disable.

```java
public class KubernetesConfigUtils {
    public static Config createKubernetesConfig(URL url) {
        Config base = Config.autoConfigure(null);
        return new ConfigBuilder(base) //
                 // ...
                .withTrustCerts(url.getParameter(TRUST_CERTS, base.isTrustCerts())) //
                .withHttp2Disable(url.getParameter(HTTP2_DISABLE, base.isHttp2Disable())) // 
                .build();
    }
}
```

### Actual Behavior

set trustCerts default value into http2Disable.

```java
public class KubernetesConfigUtils {
    public static Config createKubernetesConfig(URL url) {
        Config base = Config.autoConfigure(null);
        return new ConfigBuilder(base) //
                 // ...
                .withTrustCerts(url.getParameter(TRUST_CERTS, base.isTrustCerts())) //
                .withHttp2Disable(url.getParameter(HTTP2_DISABLE, base.isTrustCerts())) // bug
                .build();
    }
}
```
