Add warning about the editor path

[apcamargo]

This PR addresses the discussion in #832 by improving the documentation for the editor setting. It now mentions that the full path to the editor binary may be required in certain cases. Since I am unfamiliar with how Rio resolves binaries on Windows, the documentation changes are currently focused on Unix-like systems. Please feel free to expand or adjust it as needed!

As a side note, I think it's a good idea to keep that issue open if there are plans to revisit this behavior in the future. Many users likely expect that whatever is in their PATH should work seamlessly (at least, that’s my perspective).

Let's see if it happens again after your change on docs, if does then I will do a better Rio warning on the terminal and include a message like "you filled with nu but maybe you mean path/to/nu"
