Please review the jpackage fix for bug [1] at [2].
Added support for additional (macOS specific) file association
properties. These additional properties should be set via same property
file which used for file association. Names and values for properties
should match name and values as documented by Apple in
https://developer.apple.com/documentation/bundleresources/information_property_list/cfbundledocumenttypes.
jpackage will simple propagate these values to Info.plist as is.
