sig-scalability/watch-list: use n2 machine types for master instances

[p0lyn0mial]

At the moment the tests fail with (https://prow.k8s.io/job-history/gs/kubernetes-jenkins/logs/ci-kubernetes-e2e-gci-gce-scalability-watch-list-on):

ERROR: (gcloud.compute.instances.create) Could not fetch resource:
 - The selected machine type (n1-standard-32) is not compatible with CPU platform icelake Failed to create master instance due to non-retryable error

Possibly caused by kubernetes/kubernetes#118626

@aojea since @wojtek-t is unavailable can you help me merge this PR ?

There is consistent-list-from-cache-* job defined in that file that uses a n1 standard machine type but I haven't found a corresponding run for this job on the perf-dashboard so I am not sure how to check it.

I don't think I integrated the test with perf-dashboard. I just look at the results in https://testgrid.k8s.io/sig-scalability-experiments#consistent-list-from-cache-on-small-objects

@serathius it looks like your job is affected as well:

ERROR: (gcloud.compute.instances.create) Could not fetch resource:
 - Instances using machine types with more vCPUs than 64 or more memory than 455GB cannot have their minimum CPU platform set to a platform lower than 'skylake'.
Failed to create master instance due to non-retryable error
