Implement replacement countdown timer and overhaul events JavaScript

[st3phhays]

Is Your Feature Request Related To A Problem? Please describe.

As part of the ES6 conversion, the countdown library that was being. used on the events page was removed. This is due to the fact that it is very old, not maintained, dependent on jQuery, and also did not play nice with ES6. To avoid further finagling of the library, it was removed.

A custom approach can likely be implemented in plain JavaScript for a countdown timer, or there could possibly be something out there that would offer a good starting point that isn't dependent on jQuery.

In addition, the chocolatey-events.js file needs reworked to remove jQuery. Since it is no longer using the countdown library, this can be removed as well.

Describe The Solution. Why is it needed?

See above.

Additional Context.

This only effects the events are on chocolatey.org
