refactor(styles): make styles example use a const

Browse source 
This makes it easier to copy this example for use in the derive API,
like so:

```rust
const STYLES: Styles = Styles::styled()
    .header(AnsiColor::Green.on_default().bold())
    .usage(AnsiColor::Green.on_default().bold())
    .literal(AnsiColor::Blue.on_default().bold())
    .placeholder(AnsiColor::Cyan.on_default());

#[derive(Parser)]
#[clap(styles = STYLES)]
struct Cmd {
  ...
}
```

If you use the `|` method then it's not a constant function.
