Add Tern auto-installation for JavaScript

[rudolf101]

Description

The required Tern package is installed automatically if it was not found in the user's project.

• The presence of an already installed package in the user's project is taken into account.

Fixes #1780

How to test

Manual tests

Various scenarios have been tested, in the absence of the necessary package in the user directory. You can find the examples in the folder `/utbot-js/samples' and try to run UTBot with the Tern package installed or missing.
