Show "install Jupyter extension" only if users have rich output in REPL

Show "install Jupyter extension" only if users have rich output in REPL.

• Would have to first define what counts as "rich output".
• Figure out how to detect the rich output. Whether it is parsing output that we get from native repl server, or other.
• Show Install Jupyter extension to suggest ipykernel for higher fidelity options.
