[Publishing Section] Add instructions to recommit config.yaml after publishing via CI

[creativedrewy]

Right now if a publisher is using a fully CI-driven approach to dApp publishing, their config.yaml file will be changing with each minted release. If they don't re-commit that back to their version control system, that will cause major errors for subsequent releases.

Add a section to the docs that describes the need for committing config.yaml in CI context so subsequent releases will work.
