switch from open to opener

By default, `opener` launches the subprocess without waiting for its completion, compared to `open` which waits for its completion. This is helpful in case the `watch` feature is enabled and one of the following commands `watch | serve --open` is used. If this command would open the browser, listening for changes would be blocked by the browser.
