I have deploy ingress nginx have enable opentelemetry with chart version 4.9.1 and controller version 1.9.6

But data after collect only have server_name, method, host,... but not have header, body.
OpenTelemetry modules in ingress nginx cannot collect this data or missing config?

I have add `opentelemetry_capture_headers on;` to server-snippets in annotation but not effect.

```
nginx.ingress.kubernetes.io/server-snippets: |
      location / {
        opentelemetry_capture_headers on;
      }
```
