`kubectl explain` page has JSONPath identifier incorrectly generated

[Juneezee]

In the Synopsis section of the auto-generated kubectl explain page (https://kubernetes.io/docs/reference/kubectl/generated/kubectl_explain/#synopsis), the JSONPath identifier is generated as

<type>.<fieldName>[.<fieldName>]

The expected JSONPath identifier should be the same as the one in the Kubectl Reference Docs (https://kubernetes.io/docs/reference/generated/kubectl/kubectl-commands#explain)

<type>.<fieldName>[.<fieldName>]
