Description

PR #47364 introduced support for using arrays in tag attribute values.

However the feature is not currently usable because such values are rejected by the CheckDefinitionValidityPass.

How to reproduce

The following service configuration:

$configurator->services()
  ->set(Foo::class)
  ->tag('foo', ['bar' => ['baz' => 42]);

throws:

[Symfony\Component\DependencyInjection\Exception\RuntimeException]
at symfony/dependency-injection/Compiler/CheckDefinitionValidityPass.php line 67:
A "tags" attribute must be of a scalar-type for service "App\Foo", tag "foo", attribute "bar".
