Incorrect reference to caller number from Lambda function

[Zhen Qiang]

amazon-lex-connect-workshop/lab2-Building_Connect_Call_Center/myPersonalResponder_v1.js

Line 18 in a3b24ff

 const match = checkCaller(event.Details.Parameters.PhoneNumber); 

I know this is quite the old repo but for anyone unable to get the 2nd part of the workshop working, you might want to change the binding to

const match = checkCaller(event.Details.ContactData.CustomerEndpoint.Address);

in order to get caller's phone number.
