Implement hook_help()

Please review the patch.

Hi Team,

The applied cleanly and I craeted MR for this issue.

Thanks.

Thank you for your contribution! I think it can be useful to add hook_help() implementation.

I checked the hook in PR and realized that the content seems just a few first sentences copied from README.md
Maybe it's already better than nothing.

I checked and see some documentation on drupal.org that I'd like to check first

https://www.drupal.org/node/632280#s-help-page →
https://www.drupal.org/docs/develop/managing-a-drupalorg-theme-module-or... →

I still think it's not complete and maybe we can improve it to make it really valuable.
Main concerns I see:
- avoid documentation duplication;
- make it really valuable and useful;

I will bring up this question at some of the next meetings.
Set status to Needs Review.

Ok, now I realized that this issue is a duplicate of 📌 Implement hook_help() Closed: won't fix

I close it as a duplicate and we need to finish it there.
