bring back error coloring

[MarlonGamez]

Fixes: #5643
Description
Coloring on our error output has been broken since we made changes to validating color output a while ago. This change reintroduces red coloring on errors from skaffold. I've also added more validation for color, as some terminals don't support colors.

User facing changes (remove if N/A)
Users should now see errors in red when running skaffold
