Fixes for manager becoming stale

[spentacular]

Change Type (required)

Changes to the manager didn't cause the Managed Player to use the new manager because the subscription was only based on the initial Manager. This fixes a few details of the previous implementation:

1. Updates to the manager cause a new manager to be generated and persisted with a new key
2. Before the manager changes, if the previous instance was still running, terminate is called
3. Manager subscriptions now use useSyncExternalStore so they will still update outside of useEffect
4. New manager is always started instead of that being in an effect

Release Notes

Updates to the React Managed Player to ensure updates to the manager terminate the running instance and start a brand new instance.
