Issue #, if available:

Description of changes:
Update ConnectEvent Queue definition. According to Amazon Connect latest doc: https://docs.aws.amazon.com/connect/latest/adminguide/connect-lambda-functions.html#function-contact-flow, Queue is an Object. Current type definition is String, which causes parsing error

Cannot deserialize value of type `java.lang.String` from Object value (token `JsonToken.START_OBJECT`)
 at [Source: (ByteArrayInputStream); line: 1, column: 580] (through reference chain: com.amazonaws.services.lambda.runtime.events.ConnectEvent["Details"]->com.amazonaws.services.lambda.runtime.events.ConnectEvent$Details["ContactData"]->com.amazonaws.services.lambda.runtime.events.ConnectEvent$ContactData["Queue"])

Can you change this PR to target the events-v4-serialization-v2 branch please?

Also you'll need to use the Jackson annotations to be able to serialize the capitalised names like ARN, Name, OutboundCallerId, Address and Type.

"Queue": {
    "ARN": "arn:aws:connect:eu-west-2:111111111111:instance/cccccccc-bbbb-dddd-eeee-ffffffffffff/queue/aaaaaaaa-bbbb-cccc-dddd-eeeeeeeeeeee",
    "Name": "PasswordReset"
    "OutboundCallerId": {
        "Address": "+12345678903",
        "Type": "TELEPHONE_NUMBER"
    }
}
