Change LuaRocks spec url to https

[raphaelzulliger]

Hi

I'm working behind a corporate firewall which restricts SSH traffic. Therefore

luarocks install --server=https://luarocks.org/dev paths

fails at git clone. I guess, it would be easy fixable by changing the git url to https. I believe that drawbacks of doing so would be neglectable, but people like me would greatly benefit from it.

I tried to run LuaRocks against a local spec file using https. git clone succeeded, but LuaRocks failed afterwards. Thus, I'm not sure whether it can really that easily be changed. Maybe it can't or maybe LuaRocks behaves slightly different with local spec files as opposed to "official ones" on the internet
