Fix Clippy For Rust 1.72

[futursolo]

Description

Fixes #0000

This pull request fixes for Rust Release 1.72.
Rust 1.72 makes From::from a must use, which effectively makes html! a must use.

I have tried various ways to suppress unused_must_use for html!.
However, it is not effective. So I added let _ = to tests.

I have also made VNode a #[must_use] so the diagnostic will be easier to understand.

Checklist

• I have reviewed my own code
• I have added tests
