Auto installation of npm packages for JavaScript test generation

[rudolf101]

Description

If user doesn't have required npm packages for tests generation, then offer to download them automatically.

Expected behavior

In the absence of required npm packages, when trying to open a dialog window a warning appears: the npm package has not been found, it is suggested to download it by clicking OK, or cancel the operation by CANCEL.

Environment

IntelliJ Platform.

Potential alternatives

Manual downloading of required npm packages.

Context

For the convenience of using the JavaScript module, it would be good to automatically install the necessary packages so that the user does not do this manually.
