Lab Instruction should tell to hit 'enter' button to add Utterance in Language Studio

Module: 9b

Lab/Demo: 9b

Task: Create intents

Step: 2

Description of issue

Without a 'Add' button, adding utterances could be confusing.

In order to create records for utterances, need to be clearer on how to add each record by hitting enter button to add.

Too explicit - we want them to think about what they're doing.
