Added support for /v3/connect/tokeninfo endpoint

[mrashed-dev]

Description

This PR adds support for the /v3/connect/tokeninfo endpoint.

Usage

There are two methods that are part of the Auth resource that allow you to get information on a token; one for the ID token (idTokenInfo) and one for the access token (accessTokenInfo).

import Nylas, { TokenInfoResponse } from "nylas";

const nylas = new Nylas({
  apiKey: 'nylas-api-key',
});

// Get information on an ID token
nylas.auth.idTokenInfo('idToken').then((response) => {
  const idTokenInfo: TokenInfoResponse = response.data;
  // ...
});

// Get information on an access token
nylas.auth.accessTokenInfo('accessToken').then((response) => {
  const accessTokenInfo: TokenInfoResponse = response.data;
  // ...
});
