Fix appdata.xml for flatpak build #323

Closed mfschumann closed 3 months ago

mfschumann commented 3 months ago

Flatpak builder seems to be pickier when validating the appdata.xml than it used to be:

https://buildbot.flathub.org/#/builders/30/builds/12514

I cannot build the flatpak using the current appdata.xml because validation fails:

summary is longer than 35 characters
summary ends with a period
screenshots are missing captions
(128 only) mimetypes tag is deprecated

Please consider updating the appdata.xml as suggested in this PR.
