Issue title: Use default search engine to search online
 Issue body: Just like Apple's ctrl+space feature, you should be able to quickly open a new window on your default browser, and immediately search the web. This is the main reason I downloaded PowerToys, and I am disappointed this is not yet a feature. Would love to see this added.

If you'd like to see this feature implemented, add a 👍 reaction to this post.

 Comment 0: thought on implementation, could be last option.

hit up and that would go to bottom of search list.  That could solve https://github.com/microsoft/PowerToys/issues/3245.  Wouldn't return results but would solve the user choice option
 Comment 1: doing some quick run prompt tests, i don't know if we can default search.  doing msedge foobar treats it as a URL
 Comment 2: executing `THE_BROWSER "? QUERY"` will actually query.  Tested against edge and chrome and this does work.

`chrome "? foo"` and `msedge "? foo"` both worked
 Comment 3: This is fixed in 0.53, get it at https://aka.ms/installPowerToys
