need example with working path option

[jimmont]

on macOS the executablePath (and possibly other) puppeteer (possibly webdriver and playwright) options don't appear to work as expected so astral doesn't work and hangs on launch (because it's not in my path), please provide a working test example with the various suggested options; there might also be a need to comprehensively show the available options or where to find them for reference/links to that info;
