Added eID provider options object to the request body

We have updated the format of the request body for both onboarding and step-up ready-made flows.

Now, the optional documentation configurations for the VideoID process are moved to their own object called eidProviderOptions.

{
  "input": {
    "eidProviderOptions" : {
        "docTypes" : [138,169,147,245,277,134],
        "defaultId" : 138
    }
  }
}
