Update Morphs Blueprints for Laravel ^12.23 Compatibility

[pbarsallo]

I noticed my migrations began failing with an incompatible declaration error:

Declaration of PDPhilip\OpenSearch\Schema\ManagesDefaultMigrations::morphs($name, $indexNa
  me = null): void must be compatible with Illuminate\Database\Schema\Blueprint::morphs($nam
  e, $indexName = null, $after = null)

It appears the morphs type blueprints were updated to support an $after parameter in a recent change that was bundled into the Laravel 12.23.0 release.
