Missing Changelog

Hi 👋

Just as an input from someone upgrading api-pagination as a dependency: it would be nice to have a CHANGELOG.md or similar file that shows what changed between the versions. Thanks for the work on this gem! :)

Hi again, I just realized that there's a changelog in the releases, sorry. Maybe it's a good idea to link to those in a Changelog file?
