- Use the `<developer><name>` tag instead of the deprecated `<developer_name>`
- Use appstreamcli to validate appdata

The newly added developer name syntax appears not implemented
across related platforms: GNOME Software, Flathub, etc.

There is no harm in using both deprecated and newly introduced
tags together, and neither appstream-glib nor appstreamcli
fails to validate this usage.

That is also what happens in `gnome-calculator --solve`.  If it's not
done, the conversion will not work.

Fixes #368

The Troy ounce is a unit of mass commonly used for precious metals. The
price of a particular metal will primarily be listed in price per Troy
ounce.
