Add plant domain to the group integration

[McGiverGim]

Proposed change

The plant support in groups was removed and added again later here: home-assistant/core#41519
The documentation was not updated to reflect this change.

I used the UI of Github for this change, and it modifies too the latest line in the file, I don't know if this is a problem.

Type of change

• Spelling, grammar or other readability improvements (current branch).
• Adjusted missing or incorrect information in the current documentation (current branch).
• Added documentation for a new integration I'm adding to Home Assistant (next branch).
  • I've opened up a PR to add logo's and icons in Brands repository.
• Added documentation for a new feature I'm adding to Home Assistant (next branch).
• Removed stale or deprecated documentation.

Is my first PR to Home Assistant, I'm not too sure why it needs rebase. I'm up to date with the origin current branch.

It is based off, and targeting the wrong branch. As this documentation change depends on a parent PR in the codebase, it mean this documentation change only applies when a next version of Home Assistant is released.

Hence it should target the next branch. Please change the target and git rebase if needed.

Thanks @frenck, maybe I have marked the wrong options.

This change applies to the current version. The parent PR that I linked was merged into 0.116.2, but simply the documentation was not updated.

After that, do you think is better to target it for the next branch?

Thanks, @McGiverGim 👍

You are absolutely right! Merging this to current is indeed the correct move in this case.

Happy Hacktoberfest 🎉
