Docs: dmesg enricher actions + fix pod_dmesg_enricher log message

[gitanshulbisht]

Fixes #549

The dmesg enricher was already implemented (node_dmesg_enricher, pod_dmesg_enricher), but was never surfaced in the docs and pod_dmesg_enricher had a copy-paste bug in its error log. This PR:

• Adds .. robusta-action:: directives for node_dmesg_enricher and pod_dmesg_enricher in event-enrichment.rst so they appear in the docs site
• Improves both docstrings to describe what the actions do (kernel ring buffer output attached as dmesg.log)
• Fixes pod_dmesg_enricher's error message (was referencing pod_node_graph_enricher)
• Adds pod_dmesg_enricher to lightActions in the Helm chart, matching node_dmesg_enricher

Walkthrough

The change documents node and pod dmesg enrichment behavior, corrects the pod enricher’s missing-pod error text, adds both actions to the event enrichment reference, and enables pod_dmesg_enricher as a light action.
