For other fields like name, summary, description, ... the default value is in english and this is what's is currently used in the website.

<component type="desktop">
  <id>ca.desrt.dconf-editor.desktop</id>
  <name>Dconf Editor</name>
  <name xml:lang="ca">Editor del dconf</name>
    ...

I've looked at the appstream file and I can't find any tag screenshot with xml:lang, not even Thunderbird. When you have your change merged in Thunderbird and there is a new build published in flathub ping me here and I will check the how the webapp workds for this case.

Maybe this is related, but for JDownloader, the website link points to the Spanish version: https://flathub.org/apps/details/org.jdownloader.JDownloader

The website backend gets the information from the flathub appstream file located in /var/lib/flatpak/appstream/flathub/x86_64/active/appstream.xml.gz

If you extract that file and look for JDownloader you'll see that the declared homepage is the one in Spanish

 <url type="homepage">http://www.jdownloader.org/es/home/index?s=lng_es</url>
