Mention of non existant Searchable attribute on the symfony bundle

[louisboulagnon]

Hello,

The Symfony documentation references a non existant Searchable attribute,
While this seems to be worked on (meilisearch/meilisearch-symfony#387), the indices need to be configured in yaml.

The framework introduction should probably only describe the yaml way until the class attributes are available in the bundle.

documentation/getting_started/frameworks/symfony.mdx

Lines 43 to 62 in 9aaabc7

	## 3. Configure an entity for indexing
	Add the `Searchable` attribute to your Doctrine entity:
	```php
	<?php
	namespace App\Entity;
	use Doctrine\ORM\Mapping as ORM;
	use Meilisearch\Bundle\Searchable;
	#[ORM\Entity]
	#[Searchable(indexName: 'movies')]
	class Movie
	{
	#[ORM\Id]
	#[ORM\GeneratedValue]
	#[ORM\Column]
	private ?int $id = null;

Cheers

It's also outdated about the SearchService use, which is deprecated
