Removed duplicate --user-proxy-type definition

[matheusmaldaner]

Fixed argparse conflict by removing duplicate --user-proxy-type definition. This issue prevented the _cli.py from running as seen in the error below.

Command executed:
python -m magentic_ui._cli

Error:

RuntimeWarning: Couldn't find ffmpeg or avconv - defaulting to ffmpeg, but may not work
  warn("Couldn't find ffmpeg or avconv - defaulting to ffmpeg, but may not work", RuntimeWarning)

Fix:
Removed duplicate --user-proxy-type definition. I was then able to run the system in my command line interface with no issues.

To-Do:

• Document how to run the CLI locally using python -m magentic_ui._cli
