Typo suggestion prints "Did you mean ''?" when no command is close #2

Description

@pranav-dp

hey.. found a small bug when i was trying out the CLI..

when u type a command thats close to a real keyword, it gives a good suggestion like :

 $ context-dev brnd
No help topic for 'brnd'. Did you mean 'context-dev brand'?

but when the command is not close to anything, the suggestion comes out empty:

 $ context-dev qqqq
No help topic for 'qqqq'. Did you mean ''?

so it shows "Did you mean ''?" with nothing inside the quotes.

i think the cause is in pkg/cmd/suggest.go: suggestCommand always returns a
"Did you mean '...'?" string, even when it didnt find a close match. the
original urfave/cli version returns an empty string in that case, and the
caller only prints a suggestion when its not empty - so here the empty one
slips through.

happy to send a small PR for this if its useful - basically return an empty
string when nothing's close, so it just stays quiet. real typos like 'brnd'
would keep working.

side thought (separate from the bug, feel free to ignore): when nothing is
close, instead of showing nothing, maybe it could nudge people toward the
command list? something like:

 No help topic for 'qqqq'. Run 'context-dev --help' to see available commands.

or if a couple of commands are actually similar, just list those few. not sure
if that fits the direction u want - happy to help either way

                          hey.. found a small bug when i was trying out the CLI..

                          when u type a command thats close to a real keyword, it gives a good suggestion like :

                           $ context-dev brnd
                          No help topic for 'brnd'. Did you mean 'context-dev brand'?
                          

                          but when the command is not close to anything, the suggestion comes out empty:

                           $ context-dev qqqq
                          No help topic for 'qqqq'. Did you mean ''?
                          

                          so it shows "Did you mean ''?" with nothing inside the quotes.

                          i think the cause is in pkg/cmd/suggest.go: suggestCommand always returns a
                          "Did you mean '...'?" string, even when it didnt find a close match. the
                          original urfave/cli version returns an empty string in that case, and the
                          caller only prints a suggestion when its not empty - so here the empty one
                          slips through.

                          happy to send a small PR for this if its useful - basically return an empty
                          string when nothing's close, so it just stays quiet. real typos like 'brnd'
                          would keep working.

                          side thought (separate from the bug, feel free to ignore): when nothing is
                          close, instead of showing nothing, maybe it could nudge people toward the
                          command list? something like:

                           No help topic for 'qqqq'. Run 'context-dev --help' to see available commands.
                          

                          or if a couple of commands are actually similar, just list those few. not sure
                          if that fits the direction u want - happy to help either way
