Update Github Actions and Go version in sonarqube.yml

Upgraded the Go version used in Github Actions to '1.21.x' and adjusted the workflow to be triggered on both 'push' and 'pull_request' events. Removed the usage of Gosec Security Scanner and included running SonarQube analysis on both occasions.
