Add missing github registry url

[taras]

Motivation

Publish step was failing due to ENEEDAUTH error

npm error code ENEEDAUTH
npm error need auth This command requires you to be logged in to https://registry.npmjs.org/
npm error need auth You need to authorize this machine using `npm adduser`
npm error A complete log of this run can be found in: /home/runner/.npm/_logs/2025-02-08T00_34_06_419Z-debug-0.log
Error: Process completed with exit code 1.

Approach

It turns out that setup-node@v4 doesn't setup unless you provide a registry url.

# 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: ''

This has been fixed with OIDC publishing
