sonarqube scan Angular project - NODE is missing

## Affected builder image

gcr.io/$PROJECT_ID/sonar-scanner:latest

Here is my yaml file
```
steps:

- id: 'SonarQube analysis'
name: 'gcr.io/$PROJECT_ID/sonar-scanner:latest'
args:
- '-Dsonar.host.url=https://xxxxxxxxx'
- '-Dsonar.login=xxxxxxxxxx'
- '-Dsonar.projectKey=xxxxxxxxxx'
- '-Dsonar.sources=src'

timeout: "1600s"
```

## Expected Behavior

Analysis to be executed without errors

## Actual Behavior

NODE component is missing. Analysis is performed correctly, the error does not block the entire build and the SonarQube dashboard properly shows results. But without NODE I think that part of the analysis is not executed.

I'm not usre here, this is something that need to be configured at server-side or inside the sonar image?

Start with the affected gcr.io/$PROJECT_ID/sonar-scanner:latest image and the provided Cloud Build YAML. Check whether the image includes the node executable required by the SonarTS sensor, then determine whether the fix belongs in the image or server configuration. Done means the Angular scan completes without the missing Node.js error and TypeScript files are analyzed.
