extensions-app: Support "version-name" metadata field
The extensions site recently added support for a custom
"version-name" string in metadata:
gitlab.gnome.org/Infrastructure/extensions-web/-/merge_requests/154
This allows developers to control the version that is exposed to
users. As the version according to the developer is almost always
more relevant than the automatic version assigned by the website,
use it instead of the "version" field if set.
