Fix shortcut icon for .py and .bat files

[Ana06]

VM-Install-From-Zip is being used for .py and .bat files, but the icon in the shortcut doesn't seem to work well in these cases.

@emtuls this issue is related to other issues you have worked on recently. Would you like to work on it? 😄

@Ana06 Sure thing! Do you have any examples of which ones do this and what their icon's should be? Or is this something that you want to have be detected and attempt to set the shortcut icon accordingly?

• It may be possible to detect that a shortcut to a python file is being created and I could have it point to python.exe to use for the default shortcut icon if none is provided?
• Similarly, I could try to do the same for .bat files after we determine which icon to use (the normal .bat icon isn't easily available)

A quick look for Python ones show: ida.diaphora.vm and didier-stevens-beta/suite.vm and I noticed this about these packages:

• ida.diaphora.vm is not intended to be run as a python script directly, so I'm not sure if we want to modify this one?
• didier-stevens-beta/suite.vm installs a lot of tools, but each shortcut may not work properly if something like VSCode is installed, since it will ask how to open the file.
  • To mitigate this, we can use Python in the shortcut's Target so that it always knows to execute the file with Python.

For the python ones, I defaulted to using the icon from python.exe and I will also write a fix for the didier-stevens-beta/suite.vm packages so that the shortcuts work out of the box.

For .bat files, I will try to find a suitable icon to use.
