Upgrade links to HTTPS

[edent]

There are several links in .spec-data which don't use https where available.

Is it OK for me to go in an change links like this to point to https sources where appropriate?

Or do I need to change them in a specific location and regenerate them? Or have I missed the point entirely? :-)

(Was originally w3c/html#832 )

Sorry to give you a second redirect, but that file is generated from https://github.com/tobie/specref. They're quick about accepting patches, luckily. 😀

If you find fixable insecure links in other files, let me know.

Haha! No worries. Thanks :-)
