Add additional logs when embedded Node.js is not available

[zglicz]

Fixes #4563

As described in the task, we add the following logs:

1. Debug information, that the user platform is not supported
2. When the version of Node.js is unsupported, mention the possibility of setting it via the sonar.nodejs.executable property

Testing:

1. Augmented unit tests to verify that the logs get triggered
2. Manual test

• Build SonarJS
• Download SonarQube and copy the produced .jar into SonarQube extensions folder
• Change local Node version to 16
• Run Scanner on small JS project and observe in logs:
• 15:12:24.947 DEBUG: Your platform is unsupported for embedded Node.js. Falling back to host Node.js.
• 15:12:28.081 ERROR: Error during SonarScanner execution
  java.lang.IllegalStateException: Error while running Node.js. A supported version of Node.js is required for running the analysis of JS/TS files. Please make sure a supported version of Node.js is available in the PATH or an executable path is provided via 'sonar.nodejs.executable' property. Alternatively, you can exclude JS/TS files from your analysis using the 'sonar.exclusions' configuration property. See the docs for configuring the analysis environment: https://docs.sonarsource.com/sonarqube/latest/analyzing-source-code/languages/javascript-typescript-css/
