The [Built-In Value Resolvers](https://symfony.com/doc/7.1/controller/value_resolver.html#built-in-value-resolvers) list is lacking the `RequestPayloadValueResolver`. I would like to add this. I'll also link to the following related documentation: * [MapRequestPayload](https://symfony.com/doc/current/controller.html#mapping-request-payload) * [MapQueryString](https://symfony.com/doc/current/controller.html#mapping-the-whole-query-string) ❓ Should I also link *from* those articles back to the new **Built-In Value Resolvers** section that I'm creating?
