Patch a contact. `:subscriber` is an id or email. Delete stays disabled; use [Unsubscribe](/docs/api-reference/v2/subscribers-unsubscribe). Permission: `subscribers`.

Omitted `resubscribe` does **not** re-subscribe an unsubscribed contact. Optional `skipDoubleOptIn: true` promotes `PENDING_CONFIRMATION` to `SUBSCRIBED` before tag events.
