emits_changed_signal = "false" does not work

In zbus 3.10.0, setting emits_changed_signal = "false" as is described in !479 isn't working for me, busctl (from elogind) still shows the emits-change flag on the endpoint.

minimal example:

struct FooBar;

#[dbus_interface(name = "org.test.foobar")]
impl FooBar {
    #[dbus_interface(property(emits_changed_signal = "false"))]
    async fn foo(&self) -> u64 {
        0
    }
}

$ busctl --system introspect org.test.foobar /org/test/foobar

org.freedesktop.DBus.Properties     interface -         -                  -

.Set                                method    ssv       -                  -

!479 added these attributes for dbus_proxy, not dbus_interface. It would be nice to add the support for dbus_interface as well actually.

ooh thanks, I missed that.

np. I created #323 for interfaces.
