Change ps_install app icon to adaptive drawable

In the before pic, you can see that the original drawable is
small/compressed with a white ring around it. You can't really see that
in the light theme since the white ring is blended. It is much clearer in the
dark theme that this is the case.

Changing the vector drawable to adaptive-icon will fix the white ring
in the icon.
