Since the registry is deprecated, users have to build there own registry when a service locator is not enough.
However, some information can be missing, like the `supports` configuration option.

In this PR, I add the whole configuration to the tag, so everyone can build exactly what they need.

The config is added only to the `workflow` tag, not sub tags. To get it:
```php
class Kernel extends BaseKernel implements CompilerPassInterface
{
    use MicroKernelTrait;

    public function process(ContainerBuilder $container)
    {
        foreach ($container->findTaggedServiceIds('workflow.workflow') as $id => $attributes) {
            $config = $container->getDefinition($id)->getTag('workflow')[0];
            dd($config);
        }
    }
}
```
