Hello Guys! Hope all are well.
I have created a patch for hook_help for version - 8.x-1.x-dev. For me, the patch is working fine for hook_help. My Drupal version is 9.5 And PHP Version is 8.1 And my composer -2.6.
Please review my patch if it is working for you guys or not. Please do let me know. And Thank you.
I am adding a patch and screenshots for reference.

Verified and tested the #8 patch on 9.5.8, help() is added cleanly. Added screenshots for reference, RTBC++.

@Tanuja, Thank you for your confirmation.
