HexDocs for v2.0.1 incorrectly demonstrates the main function syntax

[zjcurtis]

In the quickstart

pub fn main() {
  lustre.application(init, update, view)
}

should be

pub fn main() {
  let app = lustre.application(init, update, view)
  let assert Ok(_) = lustre.start(app, "#app", Nil)

  Nil
}
