Registry-url doesn't work

[what1s1ove]

Description:
When setting registry-url the result of running npm publish --dry-run remains the default instead of the configured value.

• macOS
• Windows

Runner type:

• Hosted
• Self-hosted

Tools version:
node: v18.19.0, npm: 10.2.3

Repro steps:

name: Continuous Delivery

on:
  push:
    branches:
      - main

jobs:
  gpr-publish:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4

      - uses: actions/setup-node@v4
        with:

      - run: npm publish --dry-run

Actual behavior:
There must be https://registry.npmjs.org/ instead https://registry.npmjs.org/

I guess I found a problem.

To publish to https://npm.pkg.github.com, it is necessary for the package.json name to include a scope. However, the validation and logging process for this is so tricky. 🥲
