ci: replace deprecated SonarCloud action and bump github-script

The SonarScanner (sonarcloud-github-action) is deprecated in favour of
sonarqube-scan-action, and its internals still pull actions/cache@v4,
which targets the now-deprecated Node 20 runtime. Switch to
SonarSource/sonarqube-scan-action@v8 (runs on Node 24), setting
SONAR_HOST_URL to https://sonarcloud.io since the generic scan action
has no SonarCloud default; projectKey/organization stay in
sonar-project.properties.

Also bump actions/github-script v6 (Node 16) to v9 (Node 24) in
deploy.yml, the remaining action on a deprecated runtime.
