Subject: [PATCH] [receiver/nginx] use generated status header

This PR updates the component to generate the status table using mdatagen. Questions to the code owners:

Does this component require any of the standard warnings? See list: https://github.com/open-telemetry/opentelemetry-collector/blob/main/docs/standard-warnings.md

See related issue: https://github.com/open-telemetry/opentelemetry-collector-contrib/issues/19172
