Share wiki page edits via discourse-chat-integration plugin

For communities that use wiki pages to maintain a shared knowledge base, it would be very helpful to be notified when someone makes an edit to a topic.

At the moment, discourse-chat-integration only has the option to share new topics and replies, rather than edits to existing topics. Therefore, it would be great if the plugin could be updated to add an option to also include topic edits.

Bonus points if it includes diff details in the embed.
