Missing Cellular Handles typedefs in Doxygen of Cellular Interface lib v1.4.0

Hi There,

I found the Doxygen to lack a description. It's a small issue, but I'm posting this here as other parts may be missing.

Typedef description of CellularContext_t and CellularHandle_t are missing from v1.4.0 of doxygen.

• V1.4.0 : NG CellularContext_t and CellularHandle_t are missing
  
  https://freertos.github.io/FreeRTOS-Cellular-Interface/v1.4.0/group__cellular__datatypes__handles.html#ga2a6b2f5ebf6684559ce5865efbdd4770

• V1.3.0 : OK There are three typedef descriptions
  
  https://freertos.github.io/FreeRTOS-Cellular-Interface/v1.3.0/group__cellular__datatypes__handles.html

These missing typedefs are used int the v1.4.0 code.
