After review on apache/pulsar#25548, the two new counters emit the cursor's standard attribute set (pulsar.namespace, pulsar.managed_ledger.name, pulsar.managed_ledger.cursor.name) instead of custom managedLedger/cursor keys. Update the reference doc to match. See apache/pulsar#25548.

master(not in any released version yet).Summary
Document two new OpenTelemetry counters introduced in apache/pulsar#25548:
pulsar.broker.managed_ledger.cursor.persist.unacked_ranges.truncated— emitted when a cursor exceedsmanagedLedgerMaxUnackedRangesToPersistand ack state is truncated at persistence.pulsar.broker.managed_ledger.cursor.persist.batch_deleted_indexes.truncated— emitted when a cursor exceedsmanagedLedgerMaxBatchDeletedIndexToPersistand batch deleted index state is truncated at persistence.Both counters are tagged with the cursor's standard attributes (pulsar.namespace, pulsar.managed_ledger.name, pulsar.managed_ledger.cursor.name) — the same set used by the other cursor metrics in this section.
Added under the existing
### Managed Ledger Cursor metricssection ofreference-metrics-opentelemetry.md, following the format used by the surrounding metrics in that section.See apache/pulsar#25548.
