Use a more accurate range for CE Combine methods

Description

Fixes #18422

BEFORE

type ListBuilder() =

    member this.Yield(x) = [x]

    member this.For(m,f) =
        m |> List.collect f

    member this.Combine (a,b) =
        List.concat [a;b]

    // member this.Delay(f) = f()
    
let listBuilder = new ListBuilder()

let result = listBuilder {
    let a = 10
    yield a
    ^^^^^^^
    if true then
    ^^^^^^^^^^^^
        yield 20
        ^^^^^^^^
    else
    ^^^^
        yield 30
        ^^^^^^^^
}

After

@edgarfgp
The change looks good, the tests look good. Can you add an issue for this, and the readme information. And it's probably not WIP.

Thx
