Not all strings extracted to "strings.txt" and added to respective language *.json files

[Andygol]

While working on the Ukrainian translation of the minikube UI, I encountered an issue: that not all strings that need to be localized are present in strings.txt and the corresponding language *.json files. Some of them can be added to *.json manually, for example, as shown here.

minikube/translations/de.json

Line 48 in 71227b2

"A set of key=value pairs that describe configuration that may be passed to different components.\nThe key should be '.' separated, and the first part before the dot is the component to apply the configuration to.\nValid components are: kubelet, kubeadm, apiserver, controller-manager, etcd, proxy, scheduler\nValid kubeadm parameters:": "Eine Reihe von Schlüssel/Wert-Paaren, die eine Konfiguration beschreiben, die an verschiedene Komponenten weitergegeben wird.\nDer Schlüssel sollte durch \".\" getrennt werden. Der erste Teil vor dem Punkt bezeichnet die Komponente, auf die die Konfiguration angewendet wird.\nGültige Komponenten sind: kubelet, kubeadm, apiserver, controller-manager, etcd, proxy, scheduler\nGültige Parameter für kubeadm:",

	`A set of key=value pairs that describe configuration that may be passed to different components.

I would be very grateful if "make extract" would extract all strings that are subject to localization.

One possible reason is that the text is not properly decorated for translation, and the import section is missing "k8s.io/minikube/pkg/minikube/translate".

Many files do not contain a "minikube/translate" package in the import section, and not all strings are formatted for further translation and use.
