@dkotter It seems 10up/action-wordpress-plugin-build-zip action is not allowed to use on this repo and we might need to add it as allowed action in the list. Could you please help with check on this?

@doomholderz Wondering if this is something you can help us with again, as I know you helped allow these initially (see #23 (comment))
