TGW Peer Comments in Config Walkthrough incorrect

[apmclean]

Describe the bug
README contains example for Transit Gateway Peer import:

  toUsEast2:
    # REQUIRED: Existing Transit Gateway (see above if you're relying on vpcBuilder to create the TGW)
    existingTgwId: tgw-12345
    # REQUIRED: Existing Transit Gateway Attachment Identifier for the Direct Connect Gateway
    existingTgwPeerTransitGatewayAttachId: tgw-attach-12345
    # REQUIRED: Existing Transit Gateway Route Table associated with the Direct Connect Gateway
    existingTgwPeerTransitGatewayRouteTableId: tgw-rtb-12345

Comments indicate this should be the one for a Direct Connect gateway which is not correct.
