ModelBuilder expects a `vpc_config` data member on Networking but Networking does not have one

**PySDK Version**
- [ ] PySDK V2 (2.x)
- [ X] PySDK V3 (3.x)

**Describe the bug**
ModelBuilder expects a `vpc_config` data member on Networking but Networking does not have one

**To reproduce**
Create a ModelBuilder with a Networking argument. Attempting to run it throws an error about `Networking` not having a `vpc_config` member

**Expected behavior**
Networking can be use with `ModelBuilder`

**Screenshots or logs**
If applicable, add screenshots or logs to help explain your problem.

**System information**
A description of your system. Please provide:
- **SageMaker Python SDK version**: 3
- **Framework name (eg. PyTorch) or algorithm (eg. KMeans)**: Sklearn
- **Framework version**: 1.4.2
- **Python version**: 3.11
- **CPU or GPU**: CPU
- **Custom Docker image (Y/N)**: N

**Additional context**
Add any other context about the problem here.

まず、ModelBuilder と Networking 引数を使って失敗を再現し、次に ModelBuilder と Networking の定義を調べて vpc_config の検索処理を追跡します。Networking に期待される形を確認し、Networking を指定した ModelBuilder の構築に対する焦点を絞ったカバレッジを追加または更新します。完了の条件は、その構築で missing-member エラーが発生しなくなることです。
