Allow OPM installation with newer lua-resty-http versions

[GUI]

The pintsized/lua-resty-http git repo was renamed to ledgetech/lua-resty-http for the 0.13 release. The repo now also redirects from "pintsized" to "ledgetech" on github.com: https://github.com/pintsized/lua-resty-http

This switches the OPM dependency to the new repo name. Without this, you can't install lua-resty-openidc if you already have the newer pintsized/lua-resty-http OPM package installed, due to package conflicts:

I think that's indeed more healthy

[bodewig]

Yes, seems to be the right move.

luarocks only has 0.13 but not 0.14 which is a bit unfortunate. We probably should bump the dependency to >= 0.13 inside the rockspec as well.

I don't see why we'd need to depend on the latest if the reference is unchanged; it doesn't seem like the origin matters on luarocks/rockspec.

[bodewig]

I see. Right now the opm dependency list says we depend on a different version of lua-resty-http than the rockspec. But this probably isn't that important.
