Azure SIG CI flakes

[kkeshavamurthy]

I think the reason this Azure SIG test fail often is windows-2019 and windows-2019-containerd SIG end up with the same SIG Image Name. Whichever of the 2 builds completes second tries to create a SIG Image in the Gallery with the image name that already exists and fails.

Windows-2019 SIG image info:

�[1;32m==> sig-windows-2019-containerd: 

Image Name                : 'capi-windows-2019-1660288896

On a successful build:

seems like a variable in the scripts isn't getting set right, the original image name Image Name : 'capi-windows-2019-1660288896' should have the -containerd like the sig name that is finally stored: SIG image name : 'capi-windows-2019-containerd
