Make array_combine() generic #3351
Description
https://phpstan.org/r/59427afd-8dc6-4b14-8d40-2c52b5fc8d34
Currently, array_combine produces array|false. It should be enhanced with this:
/**
* @template TKey
* @template TValue
* @param array<TKey> $keys
* @param array<TValue> $values
*
* @return array<TKey, TValue>|false
*/
array_combine(array $keys, array $values);
