Documentation Enhancement Request: typeClassName Field in FunctionMesh CRDs

[wzhramc]

Hi everyone!

I would like to request additional documentation for the typeClassName field that appears in FunctionMesh CRDs, particularly in Input/Output configurations for Functions, Sources, and Sinks. This field appears frequently in examples but is not properly documented in the following reference pages:

https://functionmesh.io/docs/reference/crd-config/function-crd
https://functionmesh.io/docs/reference/crd-config/source-crd-config
https://functionmesh.io/docs/reference/crd-config/sink-crd-config
