[NetteUtils] Bind nette/utils rules to installed package version

[TomasVotruba]

Follows the approach of rectorphp/rector-symfony#979 for nette/utils.

Rules bound to a nette/utils version now declare the constraint themselves via ComposerPackageConstraintInterface, instead of relying on the version-named set they live in:

final class UtilsJsonStaticCallNamedArgRector extends AbstractRector implements ComposerPackageConstraintInterface
{
    public function provideComposerPackageConstraint(): ComposerPackageConstraint
    {
        return new ComposerPackageConstraint('nette/utils', '>=4.0');
    }
}

The bool $pretty / bool $forceArrays params exist from nette/utils 4.0; before that both methods took int $flags, so the named args would produce broken code.

The nette-utils4.php set becomes composer-based.php, registered as a single set - same as PHPUnit and Symfony - as every rule inside is bound to the installed nette/utils version on its own:

         if ($symfony) {
             // single set, as every rule inside is bound to the installed Symfony package version on its own
             $this->sets[] = SymfonySetList::COMPOSER_BASED;
         }
+
+        if ($netteUtils) {
+            // single set, as every rule inside is bound to the installed nette/utils version on its own
+            $this->sets[] = SetList::NETTE_UTILS_COMPOSER_BASED;
+        }

With that, the ComposerTriggeredSet in CoreSetProvider and the now unused SetGroup::NETTE_UTILS group are dropped.

Side effect: the rule is also part of named-args.php, a plain set with no composer trigger. There it now skips itself on nette/utils 3 and lower, where it used to produce broken code:

 use Nette\Utils\Json;

-$encodedJson = Json::encode($data, true);
+$encodedJson = Json::encode($data, pretty: true);

Verified with withComposerBased(netteUtils: true):

  Rule                                Package       Requires   Installed   Active
  UtilsJsonStaticCallNamedArgRector   nette/utils   >=4.0      4.1.5.0     yes
