update docs to say to fork the repo and add debug config

[cicoyle]

• Update contributing docs
  • I had a user asking how to get started with contributing, so I updated the instructions to include forking since they should be forking the repo since people wont have permissions to create a branch otherwise.
  • Added my Goland IDE config (made it generic) so it was obvious to new contributors how to build and run daprd and see their changes locally.
