Correct repository property of package.json

The repo URL needs to be prefixed with the GitHub username, i.e. jquery/eslint-config-jquery

This can also be tested by running npm repo from a terminal prompt inside 
this repo folder, it should open the default browser to https://github.com/jquery/eslint-config-jquery/

See https://docs.npmjs.com/all#repository
