Config docs generation error when inheritance is used

[brunobat]

Describe the bug

When generating the documentation from @ConfigRoot, if the interface extends another interface, the listed properties in the base interface will not include the prefix of the @ConfigMapping and are hardcoded to build time properties.

Expected behavior

When having this interface definition:

@ConfigMapping(prefix = "quarkus.otel.exporter.otlp")
@ConfigRoot(phase = ConfigPhase.RUN_TIME)
public interface OtlpExporterRuntimeConfig extends OtlpExporterConfig

Classes in the OtlpExporterConfig are displayed like:
quarkus.otel.exporter.otlp.endpoint

Actual behavior

Properties show up without prefix and are built time.

How to Reproduce?

Override a property defined on a base interface and see the generated documentation
