Status code 411 on PUT with no body

[sharwinbobde]

Hi,
I'm using keycloak crate version 21.0.101 with Keycloak 20.0.
I was trying to use the realm_users_with_id_groups_with_group_id_put method, which on execution gives a 411 response code with the message "POST requests require a Content-length header."

The workaround for me is adding .header("Content-Length", "0") to the RequestBuilder to indicate there is no body.

I'd like to patch all the empty-bodied PUT requests in generated_rest.rs
