Transferred the issue to Ballerina lang as observerbility is done at lang level. Please feel free to re-transfer if needed. @NipunaMadhushan

Noticed that the status.code tag only appears in Jaeger and not appeared in Zipkin or New Relic. Also checked whether we add a tag in the ballerina runtime with key name status.code and not found.
