Add support for translatable <p> tags in description (<p xml:lang="fr" )

[jgarciao]

According to the spec at https://www.freedesktop.org/software/appstream/docs/chap-Metadata.html#tag-description

In metainfo files, this tag should be translated by-paragraph, meaning that in a translated file, each translated <p/> child has a language property.

So this appstream entry is correct but the library doesn't handle it properly:
