first attempt to add InsertText intent

[YantCaccia]

updated:

• alexa.py (main logic)
• ./speech_assets/SampleUtterances.xx.txt (Intent)
• ./speech_assets/IntentSchema.json (Intent)
• utterances.xx.txt (Intent)
• templates.xx.yaml (answer card)

still don't know if these modifications are enough to generate the InsertText intent from 'lexigram deploy kanzi' command

Looks good, but there is a conflict on one of your files.

I was behind your latest merged PR cause you accepted it before this. Should do fine now, thank you!
