docs: Documented new IABv5 sub upgrade/downgrade and manual renewal
Documented new support for users upgrading/downgrading subscriptions
in the middle of a sub period, and for users manually renewing
before the subscription period ends. Also updated testing docs
to reflect that sandbox now supports testing subscriptions, and
documented new "autoRenewing" field in INAPP_PURCHASE_DATA.
See first comment for doc stage location.
