GLib.VariantBuilder.prototype.unref
function unref(): void { // Gjs wrapper for g_variant_builder_unref() }
Decreases the reference count on builder.
In the event that there are no more references, releases all memory associated with the GLib.VariantBuilder.
Don't call this on stack-allocated GLib.VariantBuilder instances or bad things will happen.
