Lesson refers to VS Code as an IDE

Although VS Code with extensions indeed blurs the line between a smart text editor and a fully fledged IDE, from what I have read across the software engineering industry, the general consensus is that VS Code is IDE-like with the correct extensions rather than a strict IDE. To avoid confusion, align with the wider software engineering industry and to perhaps aid clarification as to what the difference is between VS and VS Code, I think this distinction should be made in the course.

Granted, [even Microsoft are a little ambiguous](https://code.visualstudio.com/docs/supporting/faq#_what-is-the-difference-between-visual-studio-code-and-visual-studio-ide) but I think audiences would appreciate the precision.

Inizia individuando il testo della lezione che si riferisce a VS Code come a un IDE e rivedi la spiegazione circostante, inclusa la distinzione da Visual Studio. Il lavoro è completato quando il corso usa una terminologia precisa e chiarisce che VS Code è simile a un IDE con le estensioni appropriate, invece di presentarlo come un IDE in senso stretto.

Scritto dal modello di indicizzazione a partire dal testo della issue.
