[Feature] Add "Test" button to "Chrome CDP Path" config option

[jeremymeyers]

It would be good for users to be able to ensure the config is set up correctly and responding to queries. Adding a "test" button that would query the executable or url with a random string seems like a good fix.

What's now the easiest way to test that Chrome is working?

@ZobaJakColbert go to http://localhost:9222/json/version (replace localhost with IP address if you are hosting it somewhere else). If you get an output, it's running. If not, something is wrong.
