Add actual execution tests for Hyvä compatibility checker in CI

[Copilot]

The CI workflow was only testing --help output for the Hyvä compatibility checker command, which wouldn't catch runtime failures during actual module scanning.

Changes

• Added execution tests with --show-all, --third-party-only, and --show-all --detailed options
• Applied to both Elasticsearch (2.4.7) and OpenSearch (2.4.8) test jobs

echo "Test MageForge Hyvä Compatibility Check - Show all modules:"
bin/magento mageforge:hyva:compatibility:check --show-all

echo "Test MageForge Hyvä Compatibility Check - Third party only:"
bin/magento m:h:c:c --third-party-only

echo "Test MageForge Hyvä Compatibility Check - Detailed output:"
bin/magento m:h:c:c --show-all --detailed

This ensures the command performs actual compatibility scanning in CI, not just help display.
