Description of the bug
Hi team, we used a dependabot PR to upgrade the opentelementry-explorer-otlp from 0.30.0 to 0.31.0 yesterday. This also upgraded opentelemetry-common from 0.22.0 to 0.23.0.

Shortly after, we noticed our honeycomb metrics stopped working, and we started seeing the following error in production:

textPayload: "E, [2025-10-15T09:40:35.111728 #1] ERROR -- : OpenTelemetry error: unexpected error in OTLP::Exporter#encode - undefined method 'parent_span_is_remote' for an instance of OpenTelemetry::SDK::Trace::SpanData - /usr/local/bundle/ruby/3.4.0/gems/opentelemetry-exporter-otlp-0.31.0/lib/opentelemetry/exporter/otlp/exporter.rb:371:in 'OpenTelemetry::Exporter::OTLP::Exporter#as_otlp_span'"

Reverting this dependabot upgrade PR resolved the issue. We've not had a chance to dig deeper yet, but I thought I'd flag it asap in case getting the same upgrade ping experience the same issue.
