#### Description Hide error messages from "which" to avoid polluting kamctl's output (e.g. when a JSON document is returned) in environments where STDOUT and STDERR may be combined into a single stream (e.g. containers).

Without this change, kamctl's output may end up containing error messages, resulting in invalid/unparsable data. This is caused by the stdout & stderr streams being combined into a single stream in some environments, which may be outside the end-user's control (e.g. external cloud provider).
