Provider kubeconfig parameter printed in plaintext on failure

@lblackstone it appears that the issue here is trying to create a provider with the name "kubernetes":

p, err := providers.NewProvider(ctx, "kubernetes", &providers.ProviderArgs{
    Kubeconfig: pulumi.StringPtr(k.kubeConfig),
})
if err != nil {
    return errors.Wrap(err, "failed to create k8s provider")
}
_, err = helmv3.NewChart(ctx, "my-chart", helmv3.ChartArgs{
    Path:      pulumi.String(filepath.Join(chartsPath, "my-chart")),
    Namespace: pulumi.String("some-ns"),
}, pulumi.Provider(p))
if err != nil {
    return errors.Wrap(err, "failed to deploy chart")
}

failed to deploy k8s stack: failed to update stack: code: 0

Not sure if this is unintended, or just undocumneted/unvalidated.
