Based on the legacy Publish to Tableau Server tool made by Alteryx, this modification allows users to authenticate by either Username/Password or Personal Access Token (PAT).
Requires Alteryx version 2018.1 and Tableau Server 10.5 or newer.
Version 1.1 - added an optional input anchor to use externally sourced username/password or PATs
Version 1.2 - fixed some error message bugs
