When Enum has a Value Assigned, GraphQL Input does not pass the Correct Value

[ThisaruGuruge]

Description:
Consider the following code:

import ballerina/graphql;

service on new graphql:Listener(4000) {
    resource function get weekday(Weekday weekday) returns Weekday {
        return weekday;
    }
}

enum Weekday {
    # Uses the value 01
    SUNDAY = "Sunday",
    # Uses the value 02
    MONDAY = "Monday"
}

Use the following query:

{
    weekday(weekday: SUNDAY)
}

The following is the response:

{
  "data": {
    "weekday": "SUNDAY"
  }
}

But it should be the following:

{
  "data": {
    "weekday": "Sunday"
  }
}

When the resource method is executed, the weekday parameter value is the enum member name, not the value.
