Fix Fetch PRs

[joomdonation]

Pull Request for Issue # .

Summary of Changes

I use patch tester for testing PR on Joomla 4 and found that it could not fetch all the PRs (only 5 pages, mean 100 PRs). I tried to debug code and it seems Link needs to be changed to link (l in lower case). I made that change and were able to fetch all PRs.

Testing Instructions

1. Try to fetch PRs
2. Before patch: Only latest 100 PRs are fetched. After patch, all PRs are fetched.

We should check if version 3 has the same problem.
