Windows 2025 images are -gen2?

[mboersma]

Environment

• Make target: make build-azure-sig-windows-2025
• Run using container image? (Y/N): N

What steps did you take and what happened?

I ran make build-azure-sig-windows-2025 through our ADO pipeline, but it refused to promote to the community gallery because the image definition defaulted to hypervisor gen1 and apparently the image is gen2.

What did you expect to happen?

This doesn't happen for any other Azure SIG builds, so I'm assuming this target actually built a -gen2 image. But we use the convention of adding "-gen2" to those targets, so if that's the case we need to change the target name.
