Describe the solution you'd like

Here's an example of one such error:

〉ls -r js
Error: nu::parser::unknown_flag (link)

  × The `ls` command doesn't have flag `-r`.
   ╭─[entry #179:1:1]
 1 │ ls -r js
   ·     ┬
   ·     ╰── unknown flag
   ╰────
  help: use ls --help for a list of flags

I'm pretty sure Nu's commands do not have more than 8 flags, and as such, I feel like simply listing the flags for the attempted command after this error (taken directly from help) wouldn't be too major an imposition.
