Replace SonarCloud with SonarQube (#2664)

Our CI pipeline uses SonarCloud for static code analysis using the `sonarsource/sonarcloud-github-action` action. This has recently been deprecated in favour of `sonarsource/sonarqube-scan-action` following the rebranding of SonarCloud to SonarQube Cloud. This PR therefore makes the required change to `ci.yml`.

While amending this, we found an unused sonarcloud config file `src/sonar-project.properties`, which we delete.

We also resolve a code coverage issue by removing a previously-required fix; see DEFRA/water-abstraction-system#1557 for info.
