PHP8.3 compatibility fixes

[divinity76]

fixes https://github.com/coral-media/php-ml/issues/3

this was fixed automatically with Rector using the config

<?php

declare(strict_types=1);

return (static function (\Rector\Config\RectorConfig $rectorConfig): void {
    $rectorConfig->paths([
        '/home/hans/projects/php-ml/',
    ]);
    $rectorConfig->sets([
        //\Rector\Set\ValueObject\LevelSetList::UP_TO_PHP_82,
        \Rector\Set\ValueObject\LevelSetList::UP_TO_PHP_83,
    ]);
    $rectorConfig->skip([
        Rector\Php83\Rector\ClassMethod\AddOverrideAttributeToOverriddenMethodsRector::class,
        \Rector\Php80\Rector\Switch_\ChangeSwitchToMatchRector::class,
        \Rector\Php80\Rector\FunctionLike\MixedTypeRector::class,
        \Rector\Php74\Rector\Closure\ClosureToArrowFunctionRector::class,
        \Rector\Php73\Rector\FuncCall\ArrayKeyFirstLastRector::class,
        \Rector\Php80\Rector\Class_\ClassPropertyAssignToConstructorPromotionRector::class,
        \Rector\Php80\Rector\Class_\StringableForToStringRector::class,
        \Rector\Php70\Rector\FuncCall\RandomFunctionRector::class,
        \Rector\Php83\Rector\ClassConst\AddTypeToConstRector::class,
        \Rector\Php81\Rector\ClassMethod\NewInInitializerRector::class,
    ]);
});

as for why i disabled many of the rules: many of them are just personal-preference changes, and some of them break php7.4 compatibility, and none of the disabled ones are required for php8.3 compatibility.

On it, please make sure you follow conventional commits next time, I use some automation to generate CHANGELOG.MD. Rigth now is not a big deal because there is not a release yet.

@divinity76 I am merging into wip/php-8.2-deprecations to run test first. I know a lot of test are failing (related to SVM) but just making sure whatever was working before is not broken.
