Add possibility to hide the "insert code"

[codiku-dev]

Hi I really enjoy this extension I think it's amazing and super easy to use. Great job.

I thought it could be nice to be able to hide the "insert code" link below a code block. Because sometime we use codeblock just for informations or explaination but we don't want the person having the tour to be able to interact by inserting code.

Thanks :)
