Update Documentation to Reflect Fluent Bit's Ability to Capture Traces with OpenTelemetry Input Plugin along with Logs, Metrics.

The official Fluent Bit documentation currently highlights its ability to capture logs and metrics. However, with the addition of the OpenTelemetry input plugin (available in the latest versions like 3.1.8), Fluent Bit is now capable of collecting logs, metrics, and traces.

I suggest updating the documentation to reflect this expanded functionality, ensuring users are aware that Fluent Bit can capture logs, metrics, and traces via the OpenTelemetry input plugin.

At this part of the documentation, it needs to be updated
