  Starts `mix phx.server` with browser opening enabled.

  `mix star_view.server` is equivalent to:

      mix phx.server --open

  The StarView installer configures the URL as
  `https://<hyphenated-otp-app>.test:4001` in `config/dev.exs`.

  ## Options

    * `--no-open` - start the Phoenix server without opening the browser.

  Other arguments are forwarded to `mix phx.server`.
