Pull Request for PUT FAQ opened

I opened a PR for a correction in the FAQ for Where’s PUT. There is an intermittent issue where the personal website of an IETF Tools Team member. Henrik Levkowetz, will appear and redirects fail. The link was to an insecure end point as well. I updated the links to remove the redirects, use HTTPS, and reduce the occurrence of 404s when Henrik’s website would get in the way. That probably needs to be fixed at IETF. :thinking:
