[Bug] Preview docs workflow blocked by Apache security policy

### Search before asking

- [x] I searched in the [issues](https://github.com/apache/fesod/issues) and found nothing similar.

### Fesod version

1.3.0

### JDK version

N/A

### Operating system

N/A

### Steps To Reproduce

1. Create a PR that changes files in `website/` folder
2. `preview-docs.yml` workflow attempts to start
3. Workflow fails at startup with action restriction error

Failed run: https://github.com/apache/fesod/actions/runs/19072405399

### Current Behavior

The workflow fails at startup because `nwtgck/actions-netlify@v3.0` is blocked by Apache's security policy:

> "The action nwtgck/actions-netlify@v3.0 is not allowed in apache/fesod because all actions must be from a repository owned by your enterprise..."

This prevents preview deployments for documentation PRs.

### Expected Behavior

Preview deployments should work for documentation PRs.
