[TwigHooks][RFC] improving the DX

[loic425]

Before

namespace Symfony\Component\DependencyInjection\Loader\Configurator;

return static function (ContainerConfigurator $container): void {
    $container->extension('sylius_twig_hooks', [
        'hooks' => [
            'sylius_admin.book.show.content' => [
                'body' => [
                    'template' => 'library/book/show/content/body.html.twig',
                    'priority' => 100,
                ],
                 'dropdown' => [
                    'component' => DropdownComponent::class,
                    'priority' => 0,
                    'props' => [],
                ],
            ],
        ],
    ]);
};

After

namespace Symfony\Component\DependencyInjection\Loader\Configurator;

use function Sylius\TwigHooks\Loader\Configurator\component_hook;
use function Sylius\TwigHooks\Loader\Configurator\template_hook;

return static function (TwigHooksConfig $config): void {
    $config->withHookable(
        (new Hookable('sylius_admin.book.show.content'))
            ->withHook(
                (new TemplateHook('body', 'library/book/show/content/body.html.twig'))
                    ->withPriority(100)
            )     
            ->withHook(
                (new ComponentHook('dropdown', DropdownComponent::class))
                    ->withProps([])
                    ->withPriority(0)
            )     
    );
};

Going further on resource operation
Then we could go further and configure them on a specific resource operation.

#[AsResource(
   //...
    operations: [
        new Show(provider: BookItemProvider::class, hooks: [
             (new Hookable('sylius_admin.book.show.content'))
                ->withHook(
                    (new TemplateHook('body', 'library/book/show/content/body.html.twig'))
                        ->withPriority(100)
                )     
                ->withHook(
                    (new ComponentHook('dropdown', DropdownComponent::class))
                        ->withProps([])
                        ->withPriority(0)
                ) 
            ]),
    ],
)]
class ShowBookResource implements ResourceInterface

Note: In userland, we do not need to configure a lot of Twig hooks for our custom operations.
