Here I am one again #fighting against #appstreamcli validate

given this (image urls are not important here)

[...]
    <screenshots>
        <screenshot>
            <image type="source" xml:lang="en">https://[...].png</image>
        </screenshot>
        <screenshot type="default">
            <image type="source" xml:lang="en">https://[...].png</image>
        </screenshot>
    </screenshots>
[...]

appstreamcli validate complains

E: [...]: screenshot-image-source-missing
   A screenshot must have at least one image of type `source`.

... ok?

this works:

[...]
    <image type="source">https://[...].png</image>
[...]

but them flathub validation will complains that a lang attribute is required.

So here I am once again commenting out ninja test from PKGBUILD

End note:
