Change mergeable in PullRequest to Boolean

According to [1], mergeable field needs to be a null-able reference
type, and not a boolean primitive:

  The value of the mergeable attribute can be true, false, or null.
  If the value is null, then GitHub has started a background job to
  compute the mergeability. After giving the job time to complete,
  resubmit the request. When the job finishes, you will see a
  non-null value for the mergeable attribute in the response.
