Specify named argument in example of logging an image

Without specifying named argument, if we want to pass plot parameter (as in the example provided here), we receive an error, because 1st parameter is treated as file path.

Runs automatically capture file in the specified output directory, which defaults to "./outputs" for most run types.  Use upload_file only when additional files need to be uploaded or an output directory is not specified. We suggest adding `outputs` to the name so that it gets uploaded to the outputs directory. You can list all of the files that are associated with this run record by called `run.get_file_names()`|
