Add an example for when path patterns take precedence over identifier patterns

[Tomer-Eliahu]

In the Identifier Patterns section it is mentioned that path patterns take precedence over identifier patterns.

I thought adding the following example would be helpful to demonstrate this:

fn main() {

    const NUMBER: i32 = 10;
    let a = 12;
    
    match a
    {
        NUMBER => {assert_eq!(NUMBER, 10)}, //NUMBER here is 10, it does NOT shadow a
        _ => () //this catch-all is needed or we would get a non-exhaustive patterns error
    }
}

I was also wondering if this type of example is the only type there is: Are there any other types of examples where you would see this precedence taking place?
