consider adding GH Action to auto-add PRs and issues to our PACTA board

Is there any way to DRY this? By using https://github.com/RMI-PACTA/.github for example?

I worry that if we ever have to update that workflow for any reason it's going to be a huge annoying pain in the ass to do it across all our repos.

Closing this, as I now track issues on this repo in my personal maintainer board.

Also noting that we have managed to DRY this (or working towards it anyway) with this https://github.com/RMI-PACTA/actions
