docs: add a note that '@cache.locked' must be used in chain with '@cache' about cashews

Perhaps a shortcut (e.g. @locked_cache(ttl="10m")) may be more useful to mention in the first place. If someone needs more granular control or only locking, then cache.locked may be imported and used directly.

So I decided to add the lock parameter to the decorator

@cache.cache(ttl=5, lock=True)

Thanks, totally agree with you!

I don't really like functions with many arguments, so maybe we can have a shortcut like @locked_cache(ttl="10m") ?
