MapTool is registered as the default handler for *all* zip files

[duckinator]

Describe the bug
After #1856, MapTool is registered to open all zip files.

My understanding is it is related by the first line of packages/associations.properties:

mime-type=application/zip
extension=cmpgn
description=MapTool campaign save file

I believe, in theory, you could just remove the mime-type=application/zip line and it would be fine.

To Reproduce
Steps to reproduce the behavior:

1. Install MapTool
2. Open a zip file. (even with a .zip extension)

Expected behavior

I expected .zip files to open with something other than MapTool.

Screenshots
If applicable, add screenshots to help explain your problem.

cc @kayila because we talked about this a bit

Agreed. According to https://docs.oracle.com/en/java/javase/14/jpackage/support-application-features.html#GUID-324F3A7B-409A-426D-AFB1-E4540049D13E it should be possible to remove the MIME type completely (or it should be changed to application/maptool or similar).

(If we're going to modify the build process, we should also add --linux-shortcut as Debian-based Linux users have indicated they're not getting a desktop shortcut created when they install MapTool.)

Was thinking I'd just change it to mime-type=application/maptool to be in line with other application files.

It already has it as well as the menu group designation.

installerOptions += [
	'--linux-menu-group', 'Game',
	'--linux-shortcut'
]

Caused quite a bit of havoc at my end, triggering Firefox to start saving zip files as file.zip.cmpgn and always try to open them in MapTool. Worth include a fix to 1.8.4 to back-out the incorrect association too?
