`html_nested!` inserts extra pair of brackets

[Madoshakalaka]

Problem
html_nested! macro wraps the VChild with an extra pair of brackets and there's no way to fix it on the user's end.

Steps To Reproduce
Minimal code to produce:

use yew::{prelude::*};
use yew::virtual_dom::VChild;


#[function_component(MyOtherComponent)]
pub fn my_other_component() -> Html {
    html! {}
}

fn make_other_component() -> VChild<MyOtherComponent>{
    html_nested!(<MyOtherComponent/>)
}


#[function_component(MyComponent)]
fn my_component() -> Html {
    html!{
        {make_other_component()}
    }
}

fn main(){
    yew::start_app::<MyComponent>();
}

Then cargo check will give the following output:

warning: unnecessary braces around block return value
  --> src\bin\html_nested_mininal.rs:12:19
   |
12 |     html_nested!(<MyOtherComponent/>)
   |                   ^^^^^^^^^^^^^^^^ help: remove these braces
   |
   = note: `#[warn(unused_braces)]` on by default

Environment:

• Yew version: [master]
• Rust version: [1.56.0]

Questionnaire

• I'm interested in fixing this myself but don't know where to start
• I would like to fix and I have a solution
• I don't have time to fix this right now, but maybe later
