GraphQL Compiler Plugin Allows Passing an HTTP Listener with Configs to Listener Init

[ThisaruGuruge]

Description:

When used with the check expression, a GraphQL listener init function will allow passing additional configs with an HTTP listener variable.

The following should throw a compilation error, but it does not.

import ballerina/graphql;
import ballerina/http;

listener http:Listener httpListener = new(9090);
listener graphql:Listener graphqlListener = check new(httpListener, timeout = 1000);
