Add Finder's NewWindowTarget option

TODO:

Can somebody please check what values are set when the chosen option is "iCloud Drive" (it's disabled on my machine, so I can't check it myself)

I checked it with:

defaults read com.apple.Finder > before.txt
# Make the change, and try the next line a few times until the setting is persisted:
defaults read com.apple.Finder > after.txt ; git diff before.txt after.txt

rm before.txt after.txt

I had an indentation error. I've fixed it. Could you retry the CI and merge this if it's good? :)

Oh, looks like the examples are mandatory. Should they be?

The fact that we need 2 commands to change this settings breaks the architecture of the project which assumed 1 command was always sufficient. I will adapt the project architecture to be able to create these kind of complex commands.

Thanks a lot for this PR anyways, I'll update it to merge when the project is ready.
