Generic "error" message telling you to come here to write an issue and/or update the CLI

Issue

A lot of the errors in the CLI have the following generic error message:

Please check if you are using the latest version of CLI and retry the command 
If you are still facing issues, please report it on our community slack or open a GitHub issue (https://github.com/civo/cli/issues) 

For example:

$ civo kubernetes create --merge              
Please check if you are using the latest version of CLI and retry the command 
If you are still facing issues, please report it on our community slack or open a GitHub issue (https://github.com/civo/cli/issues) 
Error: you can't use --save, --switch or --merge without --wait

There are multiple issues here:

1. The generic error message does not go to stderr

For example:

$ civo kubernetes create --merge 2> /dev/null
Please check if you are using the latest version of CLI and retry the command 
If you are still facing issues, please report it on our community slack or open a GitHub issue (https://github.com/civo/cli/issues) 

All logging of this kind should go to stderr!

2. This error message is meaningless is most contexts

In the above example and in every situation I came across this error message, it was in the context of known errors due to missing flags or the like. Not due to a CLI issue that needed that required writing a GitHub issue for it.

Acceptance Criteria

Only use this error message when the error is unknown and output it to stderr
