Pull Request Overview

This PR modernizes the SonarQube integration in the CI workflow by replacing the deprecated sonar-scanner CLI tool with the official SonarSource GitHub Actions. The changes streamline the setup process and align with current best practices for SonarQube integration in GitHub workflows.

Key changes:

• Replace SonarSource/sonarcloud-github-c-cpp@v3 with SonarSource/sonarqube-scan-action/install-build-wrapper@v5 for build wrapper installation
• Replace manual sonar-scanner CLI execution with SonarSource/sonarqube-scan-action@v5 action
• Update step names to reflect the new tooling approach

• The action SonarSource/sonarqube-scan-action/install-build-wrapper@v5 does not exist. The correct action for installing the build wrapper is SonarSource/sonarcloud-github-c-cpp@v3 or you should use the main SonarSource/sonarqube-scan-action@v5 action which includes build wrapper functionality.

yes. it's also failing on main and they basically will remove it sometime in the near future. (see e.g. https://github.com/PowerGridModel/power-grid-model/actions/runs/16716376838/job/47317472386?pr=1057#step:7:30)

Run SonarSource/sonarcloud-github-c-cpp@v3
Run echo "::warning title=SonarScanner::This action is deprecated and will be removed in a future release. Please use the sonarqube-scan-action and its install-build-wrapper sub-action instead."
Warning: This action is deprecated and will be removed in a future release. Please use the sonarqube-scan-action and its install-build-wrapper sub-action instead.

I think they just did a backwards incompatible change and only updated the new action and forgot about the deprecated one. This is probably a good time to migrate
