Some friendly feedback/feature improvement

Hello @rspraymond and thank you for creating this application/plugin.

Just some friendly feedback & feature improvement suggestion.

It would be nice if the plugin could also include when it announces a new blog/page post in the chosen discord channel through the webhook a featured post meaning a preview of that published content in the Discord channel so people could read and see what the post is about instead of just a link with the name of the newly published website content.

I hope you could consider adding this as it would be a great improvement of this plugin which I think many people that are using your plugin would appreciate.

Kind regards
