Nginx lua fix

[tmiland]

• Added missing space. Closing #156
• Added lua-resty-core & lua-resty-lrucache.
• Updated lua-nginx & luajit2.

NOTE:

• This adds necessary lua_package_path directive to nginx.conf, in the http context.
  • Puts file in /etc/nginx/conf.d/lua_package_path.conf
• This adds a lib directory to /etc/nginx according to ngx_http_lua_module - install instructions for lua-resty-core & lua-resty-lrucache.
• Switches export LUA=n to export LUA=y in .github/workflows/docker/wrapper.sh
