Call for a Notifier Templating Guide

Hi all,

As discussed here Phoenix 1.7 and phasing out Phoenix.View · Issue #287 · swoosh/phoenix_swoosh · GitHub

Most people agreed that the phoenix templating ability is so powerful now and the swoosh phoenix helper library phoenix_swoosh is providing less and less valuable.

So I’m calling for a Notifier Templating Guide PR to Phoenix. @josevalim and I (and most likely more people) will review it.

Thanks all.
