Remove redundant translations

Summary:
  - Remove some redundant copies of translations after D4985.
  - Make some %d more grammatical, "run this command" reads better than "run this 1 command". In context, these numbers are always very small, so counting them even in the >1 variants aren't useful.
  - Fix subscriber(s).

Test Plan: Looked at an unsubscribe story, saw translation.
