The jpackage/internal/resources/WinResources.properties resource bundle defines the key resource.wxl-file-name which provides the associated MsiInstallerStrings.wxl value.

For example, WinResources_de.properties has resource.wxl-file-name=MsiInstallerStrings_de.wxl. However, automatic translations are based off the English source file, so the localized versions of resource.wxl-file-name are always revered to MsiInstallerStrings_en.wxl.

The non translated value should be removed from the resource bundle, and retrieved in the code programmatically.
