Disable the Chrome search engine selector by default

[dgmstuart]

In recent versions of Chrome, a search engine selection modal is shown when first opening the browser, which causes specs to fail with errors like this:

Selenium::WebDriver::Error::UnknownError:
        unknown error: failed to close window in 20 seconds
          (Session info: chrome=128.0.6613.36)

Presumably this is because the spec is trying to interact with the browser but can't get past the selection screen.

This seems to be a common issue:

Adding this option appears to fix it, but I've only tested by defining my own driver locally with this argument - not sure how I'd write a spec for this driver definition?

Also I'm not sure if this option is defined for older versions of Chrome (or is it chromedriver?) - would this result in errors when using a version where this option isn't supported?

I confirm this is a problem specifically on MacOS. It breaks headless tests. On Linux the latest Chrome doesn't show this nag screen. But it's safe to add this option on all platforms.

Interesting - If it's not there yet on Linux, then I guess it's coming - seems like it's a legal requirement that's been imposed on them by the EU so I'd expect it to eventually be on all platforms: https://www.google.com/chrome/choicescreen/
