Include Kubernetes Cluster Name in Compliance Report Output

New feature motivation

Currently, Prowler includes a context field in its compliance report when scanning Kubernetes environments. However, when executing Prowler within multiple in-cluster deployments (e.g. via CronJobs), the context field provides limited value, as it doesn't accurately reflect the originating cluster name.

Solution Proposed

Please include ACCOUNT_UID or CLUSTER_NAME field (or similar) in the compliance report output, which can be explicitly set via a flag or automatically detected from environment variable like CLUSTER_NAME) just like this is now works for general output.
