Replace .Environment.Values with .Values

Environment.Values vs Values

The {{ .Values.foo }} syntax is the recommended way of using environment values in helmfile.

Prior to this pull request, environment values were made available through the {{ .Environment.Values.foo }} syntax. This is still working but is deprecated and the new {{ .Values.foo }} syntax should be used instead.
