Update README.md with additional SonarCloud badges and improve CI workflow for coverage reporting

Enhanced the README.md file by adding new SonarCloud badges for coverage, bugs, code smells, security rating, and maintainability rating. Updated the CI workflow to remove coverage collection from the test step, as it is now handled by SonarCloud, streamlining the process and ensuring accurate badge representation.
