Update ports-and-protocols.md

[ayushpatil2122]

Description

The Ports and Protocols documentation currently describes the port range of 30000-32767 as being reserved only for TCP NodePort services. Kubernetes also uses this range for allocating UDP NodePort services, however this is undocumented

For a node port Service, Kubernetes additionally allocates a port (TCP, UDP or SCTP to match the protocol of the Service).
this is mention here about UDP protocols:https://kubernetes.io/docs/concepts/services-networking/service/#type-nodeport
