How to detect source of a dependency in go.mod

[tamal]

I am trying to convert https://github.com/appscode/voyager from glide to go mod.

I am getting an error like below:

```

go: github.com/Sirupsen/log...@v1.4.1: parsing go.mod: unexpected module path "github.com/sirupsen/logrus"

go: error loading module requirements

```

How do I find out the source of this old Sirupsen module?

Try github.com/sirupsen/log...@v1.4.1

At some point the capitalisation was changed.
