Update discord action (#486)

* Updating docker action

* adding version to message

* adding way to get PR title and body

* parsing pr body

* Updating parsing

* Updating docker workflow

* Reverting back to default variables

* fixing syntax error

* removing heading syntax

* updating parse

* Updating parsing

* Updating docker workflow
