Parsing kube config file fails when GCP auth is missing cmd-args, cmd-path

[guyrotem]

calling skuber.api.Configuration.parseKubeconfigFile() throws an exception when kube config file has a GCP user without "cmd-args" and "cmd-path" (which are optional fields).

Error thrown: Caused by: java.util.NoSuchElementException: None.get.

skuber/client/src/main/scala/skuber/api/Configuration.scala

Lines 179 to 180 in c86bdfc

	cmdPath = valueAt(config, "cmd-path"),
	cmdArgs = valueAt(config, "cmd-args")

I couldn't find the official documentation, but I have witnessed cases where gcloud CLI did not add these fields when importing a new user and I can confirm these contexts were working properly without them using kubectl (probably since "gcloud" is in my path).
Note that this exception will be thrown even when not attempting to access the malformed context.

Suggested solution: providing fallback values to GcpCommand - cmd-args: "config config-helper --format=json", cmd-path: "gcloud". WDYT?
