docs: updated badges

Fixed and updated the workflow status badges in the README. Also renamed the workflow name for pushing events from 'push' to 'cicd' since this is represented in the status badge and would sound confusing. Additionally, since OpenSSF Scorecard is no longer used, the badge was removed.
