Local Chrome driver in non-headless mode shows search engine selection

[sissbruecker]

Since Chrome 127, the browser shows a search engine selection screen every time when running tests locally:

This is problematic because:

• It is bothersome if you want to debug some test in the browser
• In at least one case with Chart ITs the dialog seems to cause tests to fail

Testbench should automatically disable the search engine selection screen by setting the argument --disable-search-engine-choice-screen (Reference).
