Update stubs, add PHP 8.5 todo

Remove comments about shouldBeQueued(true) being preferable in
production as that isn't necessarily true anymore with pending tenants
(or even the absence of any "optimizations", they're all optional).
Using queued tenant creation also requires some code changes in the
tenant onboarding logic, so it is misleading to imply that it's a
switch that should simply be turned on in production.

Add DatabaseCacheBootstrapper to config.php as it was missing there.

Remove note about MailConfigBootstrapper needing forceRefresh in the
QueueTenancyBootstrapper as we now use a non-persistent queue
bootstrapper by default.
