Add support for using Beta and Dev builds of Chrome on macOS

Chromium browsers other than Chrome (Stable) and Edge (Stable) can be used by specifying the binary_location.

Eg. Currently, this is used to specify using Brave on macOS:

binary_location="/Applications/Brave Browser.app/Contents/MacOS/Brave Browser"

Once this ticket is complete, the following should work too:

binary_location="/Applications/Google Chrome Beta.app/Contents/MacOS/Google Chrome Beta"
