Update OpenTelemetry dependencies

The otelgrpc package depedends on the core OpenTelemetry module. The
OpenTelemetry module has a peculiar construction where independent
modules reference internal types creating a lockstep upgrade that
overflows to consuming projects.

See open-telemetry/opentelemetry-go#3846 for
tracking.
