chore: bump version to 0.18.0-beta.5

[ramundomario]

This pull request includes a small change to the pyhon/__version__.py file. The change updates the version number of the project from "0.18.0-beta.4" to "0.18.0-beta.5" to be able to release a new version.

Thanks for that Kuba!

@kubasaw I have another error when saving settings for my Wine Cellar, I'll try to debug in this days 😢
Don't know if you still want to release the new beta version

@ramundomario I changed the trigger loading function (I don't fully understand what triggers are yet), which will probably temporarily silence the errors related to loading air conditioners. So I released a new version.

I'll try to merge my pydantic-based parser cleanup changes to dev before the end of the day. For now, only state readings (sensors in HA terminology) will probably work, but maybe it will be easier to troubleshoot on this version.

Anyway, thank you very much for your work. Since we're still in beta, I'm trying to release versions more frequently to learn from users what needs to be fixed perhaps.
