prometheus: Add otel_scope_schema_url and otel_scope_[attribute] labels (#5947)

Fixes https://github.com/open-telemetry/opentelemetry-go/issues/5846 Towards https://github.com/open-telemetry/opentelemetry-specification/issues/4223 (first two points from https://github.com/open-telemetry/opentelemetry-specification/issues/4223#issuecomment-2839595942) - Add instrumentation scope schema URL as `otel_scope_schema_url` label to exported metrics - Add instrumentation scope attributes as `otel_scope_[attribute]` labels to exported metrics Side notes: - The exporter does not seem to work correctly if the end user adds e.g. an `otel_scope_name` attribute. I think the exporter should ignore all attributes with names that have prefix `otel_scope_`. This scenario is also not covered by the spec. I think it may be covered by a separate PR and issue. - Removal of `otel_scope_info` metric would be handled as a separate PR. https://github.com/open-telemetry/opentelemetry-go/pull/6770
