Remove AWS auth from publish npm step (#310)

### TL;DR

Removed AWS authentication step from the npm publish workflow.

### What changed?

Removed the "Authenticate to AWS" step from the GitHub Actions workflow that publishes packages to npmjs. This step was using the AWS credentials configuration action and assuming a specific IAM role which we don't need since we switched to Trusted Publishing.
