Updating discord workflow (#474)

* Updating docker action

* adding version to message

* adding way to get PR title and body

* Adding input pass to workflows

Workflow dispatches may not get push header info. Switching logic to pass needed title and body info through just in case.

* adding token

The description on this action is awful, it didn't mention needing a token. I found this solution from the repo's issues

* parsing pr body

* Updating parsing
