Use detected chrome path as default

[dvic]

Fixes #739

@mhanberg I just modified the default_capabilities and only setting the binary option if the detection was successful.

Oops :) This breaks some tests. Looking into it.

It seems like System.find_executable returns google-chrome and not a path, I tested this on my own repo (using github action ssh debug) and it should return

iex(1)> System.find_executable("google-chrome")
"/usr/bin/google-chrome"
iex(2)> :os.type
{:unix, :linux}

Ok I think I found it 🤞: 7359523
