fix icns generation and bundle display name.

while the icns *can* be generated on linux it is much preferable to generate it on macos
it is checked in as a convience

this commit fixes the appbundle not displaying the icon corrected
and corrects the app being displayed as "python" in the top bar when the bundle is run
