chore(otel): supress unessesary warning (#11857)

Resolves: #10818

Ensure set status warning log is only generated when
`Span.set_status(...)` is called with two conflicting descriptions.
Right now this warning is logged every time the status argument is and
instance of opentelemetry.trace.Status.
