Fix broken blog post link in README (#32)

* Fix broken blog post link in README

* Fix broken `Minitest::Mock#expect` usage

In GitHub Actions, there were failing tests due to `ArgumentError`
getting thrown whenever `test/mock/rails.rb:131` was getting called. I
believe this is due to how Ruby started interpreting implicit/explicit
hash arguments, so this commit explicitly wraps the return value of the
mock in a hash.

* Retrigger GitHub Actions

For some reason an extra check showed up that no longer exists. Hoping
this fixes that.
