PySide6.QtDBus.QDBusMessage is not deepcopyable

[w568w]

What happened?

When a DBusPlugin (e.g. _Budgie, _Kde) calls DBusPlugin.create_message, an error occurs at:

Yin-Yang/yin_yang/plugins/_plugin.py

Lines 271 to 274 in f72bfff

	def create_message(self, theme: str) -> QDBusMessage:
	message = copy.deepcopy(self.base_message)
	message.setArguments([theme])
	return message

---

QDBusMessage does implement __copy__. But as the documentation says,

QDBusMessage objects are shared. Modifications made to the copy will affect the original one as well.

So it might be better to change base_message to base_message_factory (or base_message_creator)?
