Closes #162
Summary
Jekyll 4.0 caches parsed Liquid Templates. Therefore, when
{% github_edit_link %}is used through a layout or an include, there is just one instance ofJekyll::GitHubMetadata::EditLinkTagin memory.This poses a problem when attributes required for rendering the tag are memoized, resulting in the output of the same result for every page.
The changes proposed here allows compatibility with Jekyll 3.x where memoization improves performance and avoids memoizing when using Jekyll 4.0
