[PHPDoc] Prefixed template mentioning annotation with phpstan-

[mnocon]

🎫 Issue	In/a

While working on ibexa/documentation-developer#2512 we've noticed that some of the template-mentioning annotations make their way into the PHP doc.

https://ez-systems-developer-documentation--2512.com.readthedocs.build/en/2512/api/php_api/php_api_reference/classes/Ibexa-Contracts-Core-Pool-Pool.html

The PHP reference does not have a clear way of showing the template annotations - they look like a missing class, so it's best to mark them as PHPStan specific and hide them from the reference.

For QA:

Yes, templates are rather PHPStan thingy for now, so we should use phpstan annotations. Sometimes it also messes with PHPStorm (though that one got better in the recent year).

What's your POV @Steveb-p ?
