What is the URL of the page with the issue?

https://pkg.go.dev/badge/

What did you do?

I entered a URL to a GitHub repository for a Go project of mine, but inclusive of the scheme https://.

What did you expect to see?

A badge URL correctly generated with the scheme stripped but github.com maintained in the URI to the reference page for the repository.

What did you see instead?

If you enter a full URL to a GitHub repo for your Go project, including the HTTP scheme, the badge generator will strip the domain name. For example:
https://pkg.go.dev/badge/?path=https://github.com/golang/go

Will generate:

[![Go Reference](https://pkg.go.dev/badge/golang/go.svg)](https://pkg.go.dev/golang/go)

While I imagine it is expected to provide a URL without scheme as with Go imports, the resulting stripping of the domain name is counter intuitive and an issue some might not notice straight away.
