[Improvement]: Change filter definition's page limit from float to int

[dolmit-tanel-paaro]

Improvement description

I'm proposing this change because I recently run into an issue where I programmatically set filter definition's page limit:
$filterDefinition->setPageLimit(PHP_INT_MAX)

As page limit is float, PHP_INT_MAX gets converted to float: 9.2233720368548E+18
This resulted in SQL syntax error.

I don't see any practical reason for page limit to be float - you won't be loading half or 1.2 items at a time.

Ref:

ecommerce-framework-bundle/src/Model/AbstractFilterDefinition.php

Line 33 in 5e105cf

abstract public function getPageLimit(): ?float;
