Add Github Action for Publishing to Comfy Registry

[haohaocreates]

This PR adds a Github Action (publish-node-action) that will run whenever the pyproject.toml file changes. The pyproject.toml defines the custom node version you want to publish (added in another PR).

Action Required:

• [ ] Make sure the trigger branch (master or main) in publish.yaml matches the branch you want to use as the publishing branch. It will only trigger when the pyproject.toml gets updated on that branch.
• [ ] Create an api key on the Registry for publishing from Github. Instructions.
• [ ] Add it to your Github Repository Secrets as REGISTRY_ACCESS_TOKEN.

More info on the registry. Please message me on Discord if you have any questions!

Thank you, I will look into it and then proceed. This is my first GitHub project, so I need to first understand exactly what you are telling me. I will do this as soon as possible, but it will take a few days because I have a few other things on my plate.

I have joined the Discord and will get back to you. :) Thank you very much. I would appreciate more information, as I am a GitHub newbie.
