JetBrains IDE-based CDE should not depend on Node.js presence in a user's container

[azatsarynnyy]

Is your task related to a problem? Please describe

When the user starts a workspace with a JetBrains IDE from the Dashboard,
they need to make sure Node.js is present in a tools container.

Node.js is required to serve the stub web page that the Dashboard forwards to once the CDE is started:

---

This page also serves as an editor's main endpoint.

This is not a problem when starting a CDE for JS development, because the tools container always includes Node.js.
But when starting a CDE for Java development (e.g. Spring Boot stack) there's a low chance Node.js is present in a tools container.

In this case, the Dashboard forwards to itself continuously when trying to open an editor page for such a CDE:

Screen.Recording.2024-10-01.at.14.00.31.mov

Describe the solution you'd like

The editor-injector init-container should bring the Node.js binaries with all the required libraries,
and copy it to the tools container together with the editor binaries.

Describe alternatives you've considered

The user always can open CDE from the JetBrains Gateway application:

As it doesn't depend on Che Dashboard.
