docs: Update documentation to reflect changesets publish expected environment variable

[EduardoAC]

Changelog

• Documentation updated to assist with the usage of the action in combination with changesets publish

fixes changesets/changesets#942

Additional context

I wanted to add some background to this PR to provide better context for the reviewers to assist with the approval. The environment variable is defined by how NodeJS is set up within the GitHub Action Setup-node, which will automatically create a .npmrc file using this as an environment variable.

Therefore, the action expects us to use this variable over others, while if you decide to create your own .npmrc, we will be in control. As we can see on here. Hence the documentation updated to align with the previous steps above to align with the setup-node specifications mitigating potential issues when developer use the code given in the Readme

I personally had to add the registry-url for this to work:

Documentation

- uses: actions/setup-node@v4
  with:
    # Optional registry to set up for auth. Will set the registry in a project level .npmrc and .yarnrc file, 
    # and set up auth to read in from env.NODE_AUTH_TOKEN.
    # Default: ''
    registry-url: ''

The error message:

🦋  error an error occurred while publishing create-svelte-kitty: ENEEDAUTH This command requires you to be logged in to https://registry.npmjs.org/ 
🦋  error You need to authorize this machine using `npm adduser`
🦋  error npm error code ENEEDAUTH

and my setup: hyunbinseo/svelte-kitty@34a0e0a
