Add Playground setting properties through .yml or .properties

[AnneMayor]

Hi,

I am using this library(v1.0.0) to our project. It really helps a lot.
However, I would like to suggest one feature that would be more helpful.
For now, I am using Playground to provide clients(mobile, frontend) with query and parameter docs and sample test like swagger.
I found out that the default setting is schema.polling.enable = true. This leads to create many unnecessary server logs. Could you please add new setting properties like graphql-playground library?

spring:
  playground:
    enabled: true
    settings:
      schema:
        polling:
          enable: false

I found out one solution and it works well.
Therefore, I closed this issue.

graphql:
  spqr:
    playground:
      settings:
        schema:
          polling:
            enable: false

Sorry, it worked well because of browsing cache.
This issue should be handled.
