NPE in AnnotatedEndpoint with version 2.0.0 when no ServerEndpoint is configured

I tried to migrate from previous version to 2.0.0, I replaced all javax.websocket to jakarta.websocket and I'm hitting this NPE:

```

Here is the branch that I'm using https://github.com/apupier/camel-language-server/tree/tyrus.version-2.0.0-bugreport

Here is my [ServerApplicationConfig class](https://github.com/apupier/camel-language-server/blob/tyrus.version-2.0.0-bugreport/src/main/java/com/github/cameltooling/lsp/internal/websocket/CamelLSPWebSocketServerConfigProvider.java):

```
package com.github.cameltooling.lsp.internal.websocket;

import java.util.Collections;
import java.util.Set;

import jakarta.websocket.Endpoint;
import jakarta.websocket.server.ServerApplicationConfig;
import jakarta.websocket.server.ServerEndpointConfig;

public class CamelLSPWebSocketServerConfigProvider implements ServerApplicationConfig {

private static final String WEBSOCKET_CAMEL_SERVER_PATH = "/camel-language-server";

@Override
public Set getEndpointConfigs(Set> endpointClasses) {
ServerEndpointConfig conf = ServerEndpointConfig.Builder.create(CamelLSPWebSocketEndpoint.class, WEBSOCKET_CAMEL_SERVER_PATH).build();
return Collections.singleton(conf);
}

@Override
public Set> getAnnotatedEndpointClasses(Set> scanned) {
return scanned;
}

}
