fix: align remaining error messages with original distrobox

- Change "For creating it, run:" to "Ok. For creating it, run this command:"
- Use original placeholder format: <name-of-container> --image <remote>/<docker>:<tag>
- Split clone error into separate lines matching original
- Change "Next time, run:" to "next time, run this command first:"
- Improve installation error to specify distrobox-plus and missing component
