ci: add swiftv2 Linux scenario to acn pr checks

[jc2543]

Reason for Change:

This PR adds the swiftv2 e2e pr checks to the Azure Container Networking PR pipeline. This is an initial PR, and needs BYOCNI enabled for swiftv2. Once we get that enabled, we will update the cluster creation script to prevent CNS/CNI images from reconciling.

Issue Fixed:

Requirements:

• [ ] uses conventional commit messages
• [ ] includes documentation
• [ ] adds unit tests
• [ ] relevant PR labels added
