This is an awesome resource, thank you!

I noticed you use ${{ hashFiles('**/go.sum') }} as a cache key for the module cache. I am not sure that does what it is intended for, since the go.sum file does not contain a hash of the module itself, and it might be missing from a module with no dependencies. If hashFiles includes the file names in the key, you could just use the go.mod files instead, but even that would exclude modules that did not update.
