Add auto-update feature to YAML

[Vbitz]

@huiGod0328

Write a GitHub Action Workflow to each week look at all the recipes and find any recipes with a auto_update field...

e.g.

name: networkcorrespondancetoolkit
version: 0.3.3

copyright:
  - license: MIT
    url: https://github.com/rubykong/cbig_network_correspondence/blob/master/LICENCE

architectures:
  - x86_64

auto_update:
  method: github_release
  repo: rubykong/cbig_network_correspondence

If that's found then check if there's a new release using the GitHub API and if there is open an issue on the repository.

Make sure to not open duplicate issues if one's already open.
