ReturnValueMap is invalid when trying to call with same arguments but different return

[SidoniaVidican-eagleeye]

->willReturnMap([
    ['SELECT * from Cars limit 100', 100],
    ['SELECT * from Cars limit 100', 20],
]);

Trying this will always return 100, because the argument is the same in both invocations.
Could be easily fixed by changing public function invoke(Invocation $invocation): mixed inside ReturnValueMap to:

 foreach ($this->valueMap as **$key =>** $map) {
        if (!is_array($map) || $parameterCount !== (count($map) - 1)) {
            continue;
        }

        $return = array_pop($map);

        if ($invocation->parameters() === $map) {
            **unset($this->valueMap[$key]);**
            return $return;
        }
    }

This is working as intended.
