Update rector/rector requirement from ^0.15.21 to ^0.17.6

[dependabot]

Updates the requirements on rector/rector to permit the latest version.

Release notes

Sourced from rector/rector's releases.

Released Rector 0.17.6

In this release, we narrowed rules from PHPUit and Doctrine to their specific version category. We've detected few outdated and never used rules and cleaned them up to make Rector smaller and easier to use 👍

Be use to always use *SetList constants over specific rules to use the latest version:

use Rector\Config\RectorConfig;
return static function (RectorConfig $rectorConfig): void {
$rectorConfig->sets([
\Rector\PHPUnit\Set\PHPUnitLevelSetList::UP_TO_PHPUNIT_100,
]);
};
