Plugin doesn't check for format! syntax

Environment

• IntelliJ Rust plugin version: v0.4.155.4114-212
• Rust toolchain version: rustc 1.55.0
• IDE name and version: IDEA 2021.2.2
• Operating system: Windows 10

Problem description

intellij-rust doesn't check for format! syntax when using macros like println! or format!. It's probably not a big a issue but for people new to rust that are used just putting the variable into the equivalent println! of their language, it can help.

Steps to reproduce

fn main() {
    let hello = String::from("How are you doing today?");
    println!(hello);
}

The plugin doesn't give an error for the println!(hello);
