hook_help() is not implemented

Hi, I have verified this Help button missing issue with #3462362 MR applied cleanly in the D10 version.

Testing Steps:
1. Install the D10 version
2. Go to the extend tab and search for the Vipps Mobilepay module.
3. Check the Help button is missing

Testing Results
Now the Help button is appearing and working as expected.

Attaching the Before and After screenshots.
Hence it can be move to the RTBC.
RTBC+1

Thankyou !!

I don't find this text helpful in its current state so pushing back to Needs Work.
