fix(shell): update nushell completion script (#488)

Browse Source 
I've updated the completion.nu script to use nushell syntax. I tested
this with a custom cable channel and placed the keybinding logic
directly within completion.nu. Next steps will mean figuring out how to
move that logic into, I think, shell.rs.
