Magento\Framework\App\CacheInterface::load annotation is wrong

[mpchadwick]

Preconditions (*)

Install any version of Magento
Magento 2.4-develop

Steps to reproduce (*)

Implement code such as

public function __construct(
    \Magento\Framework\App\CacheInterface $cache
) {
    $this->cache = $cache;
}

public function doSomething($identifier)
{
    $cached = $this->cache->load($identifier);
    if ($cached !== false) {
}

Run a CI tool against the code (in our case Scrutinizer)

Expected result (*)

No errors reported by CI tool. Magento\Framework\App\CacheInterface can return a bool and this is the best way to validate if anything is in the cache (see: https://github.com/colinmollenhour/Cm_Cache_Backend_Redis/blob/1.14.1/Cm/Cache/Backend/Redis.php#L473 / https://github.com/colinmollenhour/Cm_Cache_Backend_Redis/blob/1.14.1/Cm/Cache/Backend/Redis.php#L488)

Actual result (*)

CI tool reports violation as Magento\Framework\App\CacheInterface::load annotation indicates only a string can be returned.
