Hi!

I'd like to suggest the addition of top-level minimal permissions on your workflow, as it would harden your security agains supply-chain attacks.

I see that you have only one workflow, the node.js.yml, but it does not specify the permissions for its jobs, letting their privileges determined by GitHub's defaults. By defining minimal permissions you would be secured against erroneous or malicious actions from external jobs you call from your workflow. It's specially important for the case they get compromised, for example.

Setting minimum permissions for workflows is recommended by GitHub itself and also by other security tools, such as Scorecards and StepSecurity.

I'd be happy to raise a PR with the changes if you agree.
