fix: Github requires authenticated channels only. (#5)

* fix: Github requires authenticated channels only.

	https://github.blog/2021-09-01-improving-git-protocol-security-github/
	Github requires using authenticated channels whenever cloning a repo,
	see: https://github.blog/2021-09-01-improving-git-protocol-security-github/#no-more-unauthenticated-git

	This change broke the `luarocks` installing script since it was using unauthenticated git:// protocol.

* Add the new version to the README file
