Fix publish GitHub Actions workflow (#3956)

* fix: dist was not built before publish to npm

- Fixes the issue that the `dist` folder was not built before publishing
  to npm. `package.json` used to include `prepare` script that runs
  `build:lib` script and `npm ci` built the `dist` folder. I removed
  `prepare` script in the commit ccbdc8e
  because `npm install` took very long. So we have to run `build:lib`
  before `publish` now.

- Updates dependencies of `npm_deploy` GitHub Actions workflow:
    - Bump Node to v18.x
