Node.js unavailable

[ptassin]

Describe the bug

During lequal/sonar-scanner execution, if .css files are found, sonar-scanner fails to launch 'node -v'

To reproduce

1. create a project containing .css files
2. declare the project in sonarqube instance
3. export variables SONAR_HOST_URL, SONAR_TOKEN, SONAR_PROJECT_KEY
4. run :

docker run --rm -u "$(id -u):$(id -g)" -e SONAR_HOST_URL="${SONAR_HOST_URL}" -v "$(pwd):/usr/src" -e SONAR_LOGIN="${SONAR_TOKEN}" -e SONAR_SCANNER_OPTS="-Dsonar.projectKey=${SONAR_PROJECT_KEY}" lequal/sonar-scanner

Expected behavior

Node.js shall be installed and java should successfully launch node -v when scanning *.css files.
