Add hook_help() to the module

Patch is working and marking it to RTBC.

The energy on this review is awesome. However, the last commit for Drupal 7 was many years ago and the Drupal 10 version of this module could use a hook_help. So this patch needs a reroll for the latest release.

Here is the updated patch. Please review.

Thanks!

Hi arpitk

I applied your patch 8 to Add to Cal module version 8.x-2.x-dev, I confirmed that the patch implemented hook_help(), however, when I visit the help page it throws an error below.

Hello Guys. Hope all are doing well.
I have installed the module on my Drupal website has version 9.5.9 And PHP version 8.1.
I hook_help for this module was implemented successfully after applying patch#8.
However, @clarkssquared mentioned He gets an error after visiting the help page. I have also the same error as you can see in my attached screenshot.
I have created an updated patch for it, which seems to be resolving the issue. I am adding my screenshots for your reference. Please have a look. And it would be great if someone can test it.
And Thank You.

Someone, Please test this patch. Thank You.
