Decouple the automatic translation and theme scripts from the IDE code

[kittaakos]

Describe the request

The following npm scripts do not require IDE2/Theia dependencies to be installed:

• "i18n:push",
• "i18n:pull",
• "themes:pull", and
• "themes:generate"

But the corresponding GH Actions run yarn and expect all the IDE2/Theia dependencies to be installed. The current way is not just inefficient but does not make much sense.

Please create dedicated npm projects inside the IDE2 project for updating the themes and translations, and run them without installing IDE2.

Describe the current behavior

See request above.
