chore: update ksm to v2.12.0

[mauri870]

Proposed commit message

We have test files for ksm v2.12.0 but the module manifest still requires v2.7.0. We need at least v2.11.0 for k8s v1.28.0 according to the versioning matrix.

See https://github.com/elastic/beats/blob/main/metricbeat/module/kubernetes/_meta/test/KSM/ksm.v2.12.0.plain.
