Nathan Dias f774e2e2e5 internal/telemetry/export/ocagent: update usages of BucketOptions to use pointers
This change updates initializations of DistributionValue to pass in a pointer for
BucketOptions rather than a value so that the custom MarshalJSON for
*BucketOptionsExplicit will be called when marshalling distributions.

Updates golang/go#33819
