ci(labeler): add sponsor/Adafruit tiers, owner skip, and discussion support

- rename priority labels usage to Prio / Prio Top
- label Adafruit members (Adafruit + Sponsor + Prio Top) and public
  GitHub sponsors by tier; contributors get Prio
- skip sponsor/Adafruit perks for the maintainer's own issues/PRs
- support discussions via the GraphQL addLabelsToLabelable mutation
