### 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();
    }
}
```

public static Config createKubernetesConfig(URL url) {
        
        Config base = Config.autoConfigure(null);
        
        return new ConfigBuilder(base) 
                .withMasterUrl(buildMasterUrl(url)) 
                .withApiVersion(url.getParameter(API_VERSION, base.getApiVersion())) 
                .withNamespace(url.getParameter(NAMESPACE, base.getNamespace())) 
                .withUsername(url.getParameter(USERNAME, base.getUsername())) 
                .withPassword(url.getParameter(PASSWORD, base.getPassword())) 
                .withOauthToken(url.getParameter(OAUTH_TOKEN, base.getOauthToken())) 
                .withCaCertFile(url.getParameter(CA_CERT_FILE, base.getCaCertFile())) 
                .withCaCertData(url.getParameter(CA_CERT_DATA, decodeBase64(base.getCaCertData()))) 
                .withClientKeyFile(url.getParameter(CLIENT_KEY_FILE, base.getClientKeyFile())) 
                .withClientKeyData(url.getParameter(CLIENT_KEY_DATA, decodeBase64(base.getClientKeyData()))) 
                .withClientCertFile(url.getParameter(CLIENT_CERT_FILE, base.getClientCertFile())) 
                .withClientCertData(url.getParameter(CLIENT_CERT_DATA, decodeBase64(base.getClientCertData()))) 
                .withClientKeyAlgo(url.getParameter(CLIENT_KEY_ALGO, base.getClientKeyAlgo()))
