fix: Fetch multiple pages from GitHub PR API (#298)

* fix: Fetch multiple pages from GitHub PR API

Previously we only fetched the first page which caused us to miss older
pull requests.

* feat: Only check as many pages as we need

Instead of checking a static x amount of pages in the API we only wanna
fetch as many pages as we actually need.
