Also rename Annotation\Route attributes to Attribute\Route on Symfony 7.x

During development on a Symfony 7.x project, I noticed a deprecated Symfony routing attribute was introduced, about which PHPStan complained.

  :27    Attribute class Symfony\Component\Routing\Annotation\Route is deprecated: since Symfony 7.4, use {@see \Symfony\Component\Routing\Attribute\Route} instead
         🪪  attribute.deprecated
  :27    Attribute references deprecated class Symfony\Component\Routing\Annotation\Route:
         since Symfony 7.4, use {@see \Symfony\Component\Routing\Attribute\Route} instead
         🪪  attribute.deprecatedClass

I was relatively sure that Rector replaced these, but it turns out it only does so on Symfony 6.4, see: https://github.com/rectorphp/rector-src/blob/b855ff8d2228d11898d847a85b36d3e55de98cb8/src/Set/ValueObject/ComposerTriggeredSet.php#L52

This is a copy of config/sets/symfony/symfony6/symfony64/symfony64-routing.php. If preferred, I could import that file into the other files instead.
