Remove any markdown json codeblock in chat actors expecting json responses

Strip any json md codeblock wrapper if exists before processing
response by output mode, extract questions chat actor. This is similar
to what is already being done by other chat actors

Useful for succesfully interpreting json output in chat actors when
using non (json) schema enforceable models like o1 and gemma-2

Use conversation helper function to centralize the json md codeblock
removal code
