fix(ci): only run npm publish on release tags (#3093)

This PR fixes the npm publish dry-run failure for prerelease versions
without changing the existing workflow trigger behavior. The publish
step now detects prerelease versions from `nodejs/package.json` and
always appends `--tag preview` when needed.

Context:
- On `main` pushes, the workflow still runs `npm publish --dry-run` by
design.
- Recent failures were caused by prerelease versions (for example
`0.27.0-beta.3`) running without `--tag`, which npm rejects.
- The previous `refs/tags/v...-beta...` check did not apply on branch
pushes, so dry-run could fail even though release tags worked.
