surface_configured in docs

[ivnsch]

The code uses this variable, but it's not declared

Add this to the fn run() function:

let mut surface_configured = false; 

It didn't appear in the website though.
It was supposed to appear after

let mut state = State::new(&window).await;

Yeap of course I added it to my code, just suggesting a minor improvement to the docs.

Just a note for anyone else stumbling across this like myself, that variable needs to be set, which I believe should be here:

state.resize(*physical_size); // this line should already exist
surface_configured = true;
