GitHub Actions — Solving actions/cache@v2 for self-hosted runners on GitHub Enterprise. GHES support.

In this story, I am going to present an alternative solution to actions/cache Github action. This solution is mostly for self-hosted runners, running actions on Github Enterprise. As actions/cache are not supported on Github Enterprise, https://github.com/actions/cache/issues/505. Also, you might have noticed a warning show that upon the cache step: Cache action is not supported on GHES.
