voluptuous.error.MultipleInvalid: extra keys not allowed @ data['availability_mode']

Describe the bug

Valetudo/lib/mqtt/homeassistant/components/HassComponent.js

Line 189 in 7d28ac8

availability_mode: "latest",

availability_mode is a relatively new attribute, unfortunately since it is not expected by hass.
home-assistant/core@d60fc0d#diff-0d67e0c95bc8b8efc20c8d5491b8ed7a6634598a9fcdc954f96a1077a2c77e7aR81
Any version prior to 2021.4.6 will probably throw an exception and not work with it.

To Reproduce

1. Install latest Home Assistant on latest packaged python on Raspbian (Home Assistant 2021.1.5), or hey actually any version before 2021.4.6, which was released JUST SEVEN DAYS AGO... https://www.home-assistant.io/blog/2021/04/07/release-20214/#release-202146---april-19
2. Update Valetudo to 2021.04.0
3. Do the workaround to rediscover mqtt devices as described on the release page
4. No longer be able to use valetudo with hass...

Vacuum Model

Roborock S5 Max

Valetudo Version

2021.04.0

Expected behavior

Additional context

Since all it does is to set the "availability_mode" to 'latest', you can just scratch that, since it's the default anyway...

Interestingly, I didn't experience any issues while testing against my local setup that is Home Assistant 2021.4.0

Either I've missed something or they've added a more tolerant error handling in a HA version newer than 2021.1.5 but older than 2021.4.6

Oh okay I see then. Disregard my comment in the PR then. I'd suggest to leave it commented in the code though, and explain why it is commented. So that someone who wants to change it to a different value gets the opportunity to think twice and make an informed choice.
