fix: Remove Pages enablement step and update permissions note

GitHub Actions cannot enable Pages automatically due to security restrictions.
Pages must be manually enabled in repository settings before deployment.

Error fixed:
- Resource not accessible by integration
- Create Pages site failed

Solution: Manual enablement required in Settings → Pages → Source: GitHub Actions
