Update LiveObjects retention docs to reflect configurable duration

Object retention is no longer fixed at 90 days — it's now configurable
between 24 hours and 90 days. Update docs to reflect this, and replace
the "contact us for configurable durations" aside with guidance to
contact Ably for retention periods longer than 90 days.

 When you update an object, the change is expressed as an [operation](/docs/liveobjects/concepts/operations). Ably sends this as an [object message](/docs/metadata-stats/stats#messages) on the channel. Like all messages, Ably stores object messages for two minutes by default.

 Operations themselves are not included in the [history](/docs/storage-history/history) or [rewind](/docs/channels/options/rewind) backlog of a channel. Instead, you should interact with objects directly via the client library.
