Switch to image entity

[tjorim]

Home Assistant 2023.7 introduces a new image entity. This seems more applicable since it does not require a continuous stream. A qr code is exactly one of the examples. There are already some platforms that use it: https://rc.home-assistant.io/blog/2023/06/28/release-20237/#image-entities

Thanks for the hint. I am going to look into it.
