Fix TS0043 Cover Controller

[ChristopheBraud]

I forgot a commit on my last PR #1076 (sorry)

As I said before, I use Open and Close action rather than toggle actions as there is already a stop button on the controller.
There's also a weird behavior with toggle actions where toggle_open stop a closing action rather than opening the cover.

I suppose this is correct for a two buttons controller, but not for a three buttons one.

Also there is a small mistake in the release notes of v4.28.0:
🎮 New devices

[TS0042](https://xaviml.github.io/controllerx/controllers/TS0042) - add device with ZHA support. [ https://github.com/xaviml/controllerx/pull/1065 ] @Strauman
[TS0043](https://xaviml.github.io/controllerx/controllers/TS0043) - add ZHA support. [ https://github.com/xaviml/controllerx/pull/1066 ] @Strauman
[TS0043](https://xaviml.github.io/controllerx/controllers/TS0043) - add cover controll with ZHA support. [ https://github.com/xaviml/controllerx/pull/1076 ] @ChristopheBraud

Last line should be Z2M, not ZHA. I don't know if you can fix it or not
