Summary

Resolves #9007
Currently running CLI command with an unrecognized parameter of length 1 results in a message containing Did you mean "$0"?

Test plan

This fix adds a check to make a suggestion only when the unrecognized cli param length is greater than 1, so that "$0" is not suggested to the user as a possible param

Added relevant tests to validateCLIOptions.test.ts

Hi and thanks a lot for the awesome first contribution!
Could you add a quick test for the > 1 and <= 1 cases please? There should already be a validateCLIOptions.test.ts or so :)
