chore: Simplify CI workflow for api-gateway by removing redundant test checks

### Summary of Changes
- Removed checks for the existence of test files and test reports in the CI workflow for `api-gateway.yml`, streamlining the process.
- Updated the workflow to focus on running unit tests and sending results to SonarQube without pre-checks.

### Expected Results
- Enhanced efficiency of the CI process by eliminating unnecessary steps, allowing for quicker feedback on code changes.
