Queries the known snippets for those matching @group, @language_id, and/or
@trigger_prefix.
If any of these are %NULL, they will be ignored when filtering the available snippets.
The [iface@Gio.ListModel] only contains information about the available snippets until
[method@Gio.ListModel.get_item] is called for a specific snippet. This helps reduce
the number of [class@GObject.Object]'s that are created at runtime to those needed by
the calling application.
