Implement TODO: check the init match Response type

[h3ssan]

Overview

In this PR, I did Implement the TODO in src/handler.ts, which is to make sure the contents of init match ResponseInit.

The implemented code:

/** Checks whether the passed value is the `graphql-http` server agnostic response. */
function isResponse(val: unknown): val is Response {
  // Make sure the contents of body match string | null
  if (!Array.isArray(val)) return false;
  if (typeof val[0] !== 'string' || val[0] !== null) return false;
  if (!isObject(val[1])) return false;

  // Make sure the contents of init match ResponseInit
  const init = val[1];
  if (typeof init.status !== 'number') return false;
  if (typeof init.statusText !== 'string') return false;
  if (init.headers && !isObject(init.headers)) return false;

  return true;
}

Please test the implemented code further more. Thank you!
