Update php requirements : PHP >= 7.3+

Correct also some warnings in PHP 8+ and PHP 8.2

Au final j’ai appliqué un coup de ECS, même si certaines règles s’éloignent un peu de ce qui est fait chez SPIP.

<?php

// ecs.php
use PhpCsFixer\Fixer\Phpdoc\GeneralPhpdocAnnotationRemoveFixer;
use PhpCsFixer\Fixer\Strict\DeclareStrictTypesFixer;
use PHP_CodeSniffer\Standards\Generic\Sniffs\CodeAnalysis\AssignmentInConditionSniff;
use Symplify\EasyCodingStandard\Config\ECSConfig;
use Symplify\EasyCodingStandard\ValueObject\Set\SetList;

return static function (ECSConfig $ecsConfig): void {
    $ecsConfig->sets([
        SetList::PSR_12, 
        SetList::SYMPLIFY, 
        SetList::COMMON, 
        SetList::CLEAN_CODE
    ]);
    $ecsConfig->skip([
        DeclareStrictTypesFixer::class, 
        AssignmentInConditionSniff::class,
        DeclareStrictTypesFixer::class,
        GeneralPhpdocAnnotationRemoveFixer::class,
    ]);
    $ecsConfig->indentation('tab');
    $ecsConfig->paths(['AdaptiveImages.php']);
};
