Make hvac_action optional on ulm_translation_hvac

[mpeterson]

Some climate entities do not have the hvac_action attribute and in those
cases the translation ends up with '(undefined)' as the mode part. This
is undesirable, and thus this PR removes it from the translation in case
there is no hvac_action attribute.

@basbruss Thanks, I didn't know. I did look for a CONTRIBUTE.md file but couldn't find any and now after you told me looked again and still can't find any. Are you sure there is one?

In any case I rebased and changed base branch.

@basbruss found it in .github ! I'll read it now

It is located in the .github folder: https://github.com/UI-Lovelace-Minimalist/UI/blob/main/.github/CONTRIBUTING.md
And there are also references underneath a PR added by Github. (But are not that prominent placed)

Thanks for your contributions 😉

Oh, wow. I would have never seen that small information block from GitHub. Really bad placement there :)

Thanks for your contributions 😉

for sure! Thanks to you and all the other maintainers. I really enjoy using the project.
