We will need a new v6 tag with this.

cc @F0bes Not sure if you got my ping on Matrix, but you should update the action to this commit or the next v6 tag, which will have it.

Ping @stenzek as well.

@past-due you have to add --compose-url-policy=full after --mirror-screenshot-url here https://github.com/Warzone2100/warzone2100/blob/beb73f7934df061873f4e43ab3a62d38c69aca28/.ci/flatpak/build.sh#L37
