Repository: prometheus/prometheus (language: go)

Issue:
Broken link in readme
### What did you do?

I tried to open [prometheus.io](https://prometheus.io/) from the first 2 links in the readme from github mobile

### What did you expect to see?

Expected to be redirected to https://prometheus.io/ like on desktop

### What did you see instead? Under which circumstances?

Redirected me to `http://github.com//prometheus.io` instead of `https://prometheus.io`. This was just when I was using github mobile and it works when github is accessed through a browser.
