v3.1.48+1-centreon

Actually, smarty-php/smarty 3.1.48 cannot be installed on centreon 22.10, 23.04, 23.10 because the PHP requirement is 7.2.
This PR corrects the PHP configuration required to install this version on PHP 8.1. A fork of smarty-php/smarty was required.

Two branches has been created to manage the next releases : dev-3.1.48.x for development branche and 3.1.48.x for stable branche.

The tags will be in this following format : v.3.1.48+*-centreon where * is the minor of centreon.

Change
