Use standard subscribers effects in Herald Adapter for Phriction

Summary: Ref T8455. Instead of using an ad-hoc subscribers effect in Phriction, use the new standard one (introduced previously; this depends on D13178).

Test Plan:
  - Wrote an "add subscribers" Herald rule, updated a Phriction document, saw it apply its effect.
  - Observed availability of "remove" subscribers actions.
