Google_Http_MediaFileUpload PHPDoc issues? #1881

I've been using Google_Http_MediaFileUpload to upload videos to YouTube. I have no issue with the actual functionalities of the code, only with the type hinting that seems to be incorrect for a lot of the constructor / methods parameters.

Code example

The following code is mostly taken from the documentation.

$chunkSizeBytes = 10 * 1024 * 1024; // 10 MB
$fileSize = filesize($videoFile->getRealPath());

$this->googleClient->setDefer(true);

$insertRequest = $ytService->videos->insert(
    'snippet,status',
    $ytVideo
);

$media = new \Google_Http_MediaFileUpload($this->googleClient, $insertRequest, 'video/*', null, true, $chunkSizeBytes);
$media->setFileSize($fileSize);

This works perfectly fine, but triggers a lot of linting warnings from, for example, PHPStan or Intelephense in VSCode, because of the PHPDoc block of Google_Http_MediaFileUpload constructor.

Here's the warnings:

Parameter #2 $request of class Google_Http_MediaFileUpload constructor expects 'Psr\Http\Message\RequestInterface', 'Google_Service_YouTube_Video' given.
Parameter #4 $data of class Google_Http_MediaFileUpload constructor expects string, null given.
Parameter #6 $chunkSize of class Google_Http_MediaFileUpload constructor expects bool, int given.

For the first, I'm not really sure what's the issue here. Using the result of $ytService->videos->insert is what the doc says to do, but the returned type is not compatible at all (but it works when it actually runs, so it's correct...)

Is it intentional that $chunkSize is defined as a bool (seems weird to me, but maybe there's a reason)? $data should also specify |null.
