[TT-8663] Improve GraphQL "depth limit exceeded" error message

[furkansenharputlu]

As a user, I want to see max depth limit and current depth limit info too when I get a depth limit exceed, so that I can understand what I am doing wrong easily.

Acceptance Criteria

• Discuss with the squad that whether it is a security issue
• The response should show the current depth and the max depth limit

Details

It is a customer request from webinar: https://www.youtube.com/watch?v=9nF_piFQ-D8

Instead of this:

{
    "error": "depth limit exceeded"
}

Better this:

{
    "error": "query depth limit exceeded - current: 3 > max: 2"
}

My comment: This is not a security thing. An attacker still can learn what is the depth limit value in 2 seconds. The point is to help users to use the API easily.
