This was partially discussed in #2.

Currently, the cache-registries input is false by default because it may actually slow down running time on Windows. Many people will probably not notice this input and leave it on false or can't be bothered to ensure that this input is only set to true on non-Windows operating systems.

So, should we check whether the user didn't set anything and when the operating system is Ubuntu or macOS, then set cache-registries: true?
