Prototype an assistant in the docs returns a 422 error

Hey there!

I was just reading up the new documentation and quickly tried the Prototype an assitant part. I changed a bit the training data and clicked on Train and nothing happened. Looking at the network tab, I saw that the training request returned the following error:

{
"version":"2.0.0rc2",
"status":"failure",
"message":"NLU training data exceeds size limit of 100.",
"reason":"TrainingError",
"details":{},
"help":null,
"code":422
}

Would be cool to have the error pop-up in the front-end and to have an idea of what’s the limit we can play with with the prototype!
