meta: use consistent terminology in mod policy

* Moderation Policy: Use consistent terminology

Bans are definted as _temporary_ or _indefinite_, but then usage later
on is all about _temporary_ vs. _permanent_. This change makes the
terminology consistent throughout the policy.

Additionally, it re-orders some text so that _temporary_ always appears
before _indefinite_.
