Migrate from moment.js to Luxon

[parkr]

We only need to convert one line of moment.js to Luxon:

gossip/public/assets/messages.js

Line 18 in d2258b1

els[i].dataset.fromDate = moment(els[i].innerText).fromNow();

All this code is doing is taking an ISO date and converting it to a human "ago" phrase like "3 minutes ago" or "1 year ago", etc.

Here's an idea of how to accomplish this with Luxon: moment/luxon#274 (comment)

Dang, Luxon.min.js is 68K and moment.min.js is only 58K. For simplicity's sake, I'll stay with moment until it's truly retired.

Luxon v2 - https://moment.github.io/luxon/#/moment?id=humanization

import { DateTime } from 'luxon';
const isoDate = '2021-08-26T08:19:40.342+00:00';
const ago = DateTime.fromISO(isoDate).toRelative();
console.log(ago); // '8 hours ago'
