Skip appstream/appdata file elements with translate="no" attribute
Appstream format (informally? only indirectly mentioned) recommends the use of the translate
attribute with "no"`value to mark elements not to get translations.
Currently scripty is not aware of that and handles those elements for translation.
Example (https://invent.kde.org/multimedia/kdenlive/-/blob/master/data/org.kde.kdenlive.appdata.xml#L6):
<developer_name translate="no">KDE</developer_name>
<developer_name translate="no" xml:lang="ar">كِيدِي</developer_name>
<developer_name translate="no" xml:lang="ca">KDE</developer_name>
<!-- ... -->
That attribute seems to be used for any element type which is candidate for translations. See https://docs.flathub.org/docs/for-app-authors/metainfo-guidelines/#metainfo-translations for some more detailed notes:
By default elements in MetaInfo that can be translatable will be marked as such. However translate="no" can be used to explicitly mark them as forbidden. The whole block of the description tag can be excluded by using translate="no".
https://www.freedesktop.org/software/appstream/docs/sect-Quickstart-Translation.html itself as of now does not mention that.
Where the attribute is from is unclear ATM, could not find a DTD or XSD file for the metainfo XML schema. So one has to guess from the docs...
