Documentation regarding return types is incorrect

For example...

ZRangeByScore... README says...

Return value Array containing the values in specified range.

However, the declaration disagrees...

https://github.com/phpredis/phpredis/blob/2acab399cb667475569e313bd688f5f19665c7e4/redis.stub.php#L4457

public function zRangeByScore(string $key, string $start, string $end, array $options = []): Redis|array|false;

Which says that return types can be Redis, array or false.

This may seem trivial, but if you take the documentation at its word when using the extension it's asking for run time type errors.

I would have thought there are (many?) other instances but this is the one that I came across.
