fix(BrowserApplicationEntity): addition of browserProperties fields

[pranav-new-relic]

newrelic-client-go changes required by newrelic/terraform-provider-newrelic#2421.

Kindly head over to the PR linked above for more context on the necessity of these changes :) a detailed description has been attached.

However, a TL;DR version of this is below - the changes add the following fields to the getEntity and getEntities queries.

When a BrowserApplicationEntity is queried, the response comprises jsConfig inside browserProperties, that contains the following information (sensitive details redacted)

Request

{
  actor {
    entity(guid: "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX") {
      ... on BrowserApplicationEntity {
        guid
        name
        browserProperties {
          jsConfig
          jsConfigScript
          jsLoaderScript
        }
      }
    }
  }
}
