🌱 test/e2e: Extend ClusterClass changes test to cover InfrastructureMachineTemplate rotation

[sbueringer]

Signed-off-by: Stefan Büringer [email protected]

What this PR does / why we need it:
This PR extends the ClusterClass changes e2e test to cover InfrastructureMachineTemplate rotation. This makes it easy to test if the webhook change for ClusterClass SSA has been implemented correctly.

xref: https://cluster-api.sigs.k8s.io/developer/providers/v1.1-to-v1.2.html#required-api-changes-for-providers (2nd point)

I would like to cherry-pick this in to release-1.2 to make it directly available to providers adopting CAPI v1.2

Which issue(s) this PR fixes (optional, in fixes #<issue number>(, fixes #<issue_number>, ...) format, will close the issue(s) when PR gets merged):
