Any reason why receive_batch_multipart requires 'static for body?

[XiNiHa]

While updating the Rocket integration for 0.5.0-rc.1, I found that it is not possible to use async_graphql::http::receive_batch_body since it requires 'static lifetime for the data parameter and the recent Rocket version changed to require the lifetime of the body data to be the same with the lifetime of the request.

However, removing 'static requirement from both receive_batch_body and receive_batch_multipart simply fixed all the issues without any errors. Is there any specific reason that data parameter of receive_batch_multipart should be marked as 'static? Otherwise, I'll just make a pull request with the 'static requirement removed.

It seems that this 'static is unnecessary. 😁

I tried to remove the 'static constraint on the body, and no problem was found.
