Describe the bug
The helm.Upgrade is always using the latest version of the chart to install the new version and ignoring the version value in the helm.Options parameter, which should be honored.

To Reproduce
Steps to reproduce the behavior, code snippets and examples which can be used to reproduce the issue.

helmOpts := &helm.Options{
		SetValues:      values,
		KubectlOptions: c.GetKubectlOptions(Config.KumaNamespace),
                 Version: c.opts.helmChartVersion,
	}
helm.UpgradeE(c.t, helmOpts, "chart-repo/chart-name", "my-release")
