11-11: Documentation updates are accurate and correctly reference the official Fluent Bit metrics plugin.

The changes consistently replace Node Exporter references with fluentbit_metrics, which is the correct official plugin name per Fluent Bit documentation. Parameter descriptions (e.g., scrape_interval for internal metrics) and configuration examples are aligned with the plugin's actual behavior. The intentional retention of the Node Exporter reference in line 7 as a processing comparison is appropriate.
