run 'go mod tidy' in the cli directory to fix inconsistent vendoring

[johanneskastl]

While packaging the CLI for openSUSE (to be able to play with it), I found that the vendoring in the cli directory is inconsistent. This PR fixes it for now.

It would still be necessary to make sure it stays consistent for any changes to the cli directory's go.mod or go.sum files.
