ci: Use the latest tag for SonarCloud versioning

Configure SonarCloud to use the latest git tag as the version identifier
instead of the current commit. This ensures that SonarCloud considers
all code changes since the last tagged release, aligning with our setup
to track new code issues from the most recent release.
