Pull request overview

This PR implements support for configuring GKE “private nodes” when creating a cluster on GCP with a user-provided (existing) VPC, and ensures the selected value is propagated through the creation payload and shown in summaries/settings.

Changes:

• Bumps qovery-typescript-axios to include the latest API contract needed for the new feature field(s).
• Adds private_nodes to the GCP existing VPC feature data model and cluster creation payload building.
• Updates UI (feature step, summary, and network settings read-only display) and adds/updates unit tests accordingly.
