Pick-up .desktop file association patch

I've written this patch:
https://github.com/ares-emulator/ares/pull/2622
so that Ares could be automatically associated with the ROM types it supports. That also means that ares would be offered as an option to handle, say, WonderSwan ROMs, which would make it the only emulator on Flathub to be able to do so.

Patch is trivial, and that's how I tested the patch.

```diff
diff --git a/dev.ares.ares.yaml b/dev.ares.ares.yaml

Review pull request #2622 and dev.ares.ares.yaml first, then inspect the referenced patch path in the Flatpak module definition. Confirm that the build registers the supported ROM types so Ares is offered as a handler on Flathub.
