Portable executable not supported for non-exe targets

Brief description of your issue

When trying to create a package for PlantUML, I found that the .jar file was renamed by winget-cli from plantuml.jar to plantuml.exe. This prevents packages of non-executable.

Steps to reproduce

Grab the manifest from here:

1. https://github.com/microsoft/winget-pkgs/pull/110767
2. run winget install --manifest F:\Files\Git\winget-pkgs-1\manifests\p\PlantUML\PlantUML\v1.2023.9\
3. open up the directory which it was installed, for me this was C:\Users\David\AppData\Local\Microsoft\WinGet\Packages\PlantUML.PlantUML__DefaultSource.

Expected behavior

The file saved as plantuml.jar

Actual behavior

The file is renamed to plantuml.jar.exe

Reproduce the issue with the PlantUML manifest from microsoft/winget-pkgs pull request 110767 and the documented winget install command. Trace how winget-cli handles the downloaded .jar for a non-exe target; done means the installed file remains plantuml.jar instead of being renamed to plantuml.jar.exe.
