Subject: [PATCH] [Serializer] Add missing json parameter

In the `Deserializing Input Partially (Unwrapping)` section, the code sample is missing the `'json'` format specifier as the third argument when calling `deserialize`.

This commit adds the missing format value into the function call of the code sample.

Function signature: https://github.com/symfony/symfony/blob/6.4/src/Symfony/Component/Serializer/Serializer.php#L146
