CI: add workflow to test node-operators documentation scripts

Created a new CI workflow to test the node-operators documentation
scripts, ensuring the build-info command examples work correctly
across different platforms.

The workflow tests:
- build-info-docker.sh - Basic Docker build-info command
- build-info-docker-version.sh - Version-specific build-info
- verify-build-info-docker.sh - Build-info verification with grep

Tested on: ubuntu-22.04, ubuntu-24.04, macos-latest

Changes:
- Added .github/workflows/test-docs-scripts-node-operators.yaml
