automatic insertion of pbh.backticks_to_code() is causing problems

[firasm]

Discovered while debugging the issue resolved by PR #83 (but it doesn't solve this issue).

In terms of flow, I would like pbh.backticks_to_code_tags(data2) to appear before data.update(data2), but because data.update(data2) has been added manually in every question, we probably need to remove data.update(data2) from all questions, and then add it back in algorithmically, at the same time as pbh.backticks_to_code...

So the final form would look something like:

def generate(data):
    
    ...
    
    # The following code is added in by problem bank scripts automatically to
    # convert backticks to codeblocks/code fences in answers text.
    # This line can be commented out to disable
    pbh.backticks_to_code_tags(data)
    # End code added in by problem bank scripts

    # Update the data object with a new dict
    data.update(data2)

def prepare(data):
    pass

This will be messy...
