Check max PHP version compatibility

Current last PrestaShop version isn't compatible with last PHP versions (≥8.2), it would be nice if this tool can notice if current PHP version is too new for PrestaShop.

I improved the script by detecting the current PrestaShop version of the shop and displays related PHP versions :
