dubhe: recipes: Update github.com urls to use https
Github has announced there will be no more git:// fetching from their
servers:
https://github.blog/2021-09-01-improving-git-protocol-security-github/#no-more-unauthenticated-git
and they're about to start having brownout periods to encourage people
to update. This runs the conversion script over OE-Core to update our
urls to use https instead of git.
