Typo correction for not-found shell commands

1. Install suggest-command-not-found

   $ cargo install suggest-command-not-found

2. Add command_not_found_handler to your ~/.zshrc

   command_not_found_handler() {
     if command -v suggest-command-not-found &> /dev/null; then
       exec suggest-command-not-found $@
     else
       echo "zsh: command not found: $@"
     fi
   }

   Or update your ~/.bash_profile if you are using Bash:

   command_not_found_handle() {
     if command -v suggest-command-not-found &> /dev/null; then
       exec suggest-command-not-found $@
     else
       echo "bash: command not found: $@"
     fi
   }

3. Make a typo

   $ carog new mypj
   Error: command not found: "carog" new mypj
      ==> Did you mean "cargo"?
   
   $ notacommand
   Error: command not found: "notacommand"
   
   $ echo $?
