fix: Connector "Type" cannot be Serverless resource types

[GavinZZ]

Issue #, if available

Description of changes

There is a connector bug when using RoleName + Type.

MyReadConnector:
    Type: AWS::Serverless::Connector
    Properties:
      Source:
        Type: AWS::Serverless::Function
        RoleName: MyRole
      Destination:
        Id: MyTable
      Permissions:
      - Read

Because we didn't input Id, it will directly use Type and try to find a profile using AWS::Serverless::Function to AWS::DynamoDB::Table. It will fail because not such profile is found. We should be using AWS::lambda::Function instead.
