Subject: [PATCH] fix(exposition): export internal package for OSGi resolution

prometheus-metrics-exposition-textformats imports
io.prometheus.metrics.expositionformats.internal because
PrometheusProtobufWriter loads the protobuf implementation via
Class.forName, but the exposition-formats bundles kept that package
private. Export it via bnd _exportcontents so OSGi can wire the two
bundles together.
