📅 Integrate the existing GCal into the events page

There is a Google Cal that @lili2311 and I update when we can with events. This should be integrated onto the events page to display upcoming WHFNP events on the website

Before going ahead with this one, we need to get wireframes and so on going. The gcal is not a good one to use for the events. Meetup would be better so we would need to see what can be done with meetup instead.
