Launch file uses clucky, testbed, auto. Node was using core, testbed, auto. Replaced core with clucky in the node.

7669ded344 feat(core): add code support for testbed
Adds parameter `is_testbed`. WIP: still needs support in astra_descriptions; new parameter will not be usable until then. When using an incorrect parameter value, odom will be incorrect and will drive at a scaled speed from requested over cmd_vel.

### Using the Mock Connector
Anchor provides a mock connector meant for testing and scripting purposes. You can select the mock connector by running anchor with this command:
```bash
$ ros2 launch anchor_pkg rover.launch.py connector:="mock"
```
To see all data that would be sent over the CAN network (and thus to the microcontrollers), use this command:
```bash
$ ros2 topic echo /anchor/to_vic/debug
```
To send data to the mock connector (as if you were a ROS2 node), use the normal relay topic:
```bash
$ ros2 topic pub /anchor/to_vic/relay astra_msgs/msg/VicCAN '{mcu_name: "core", command_id: 50, data: [0.0, 2.0, 0.0, 1.0]}'
```
To send data to the mock connector (as if you were a microcontroller), publish to the dedicated topic:
```bash
$ ros2 topic pub /anchor/from_vic/mock_mcu astra_msgs/msg/VicCAN '{mcu_name: "arm", command_id: 55, data: [0.0, 450.0, 900.0, 0.0]}'
```

When you go to run anchor, use the `PORT_OVERRIDE` environment variable to point it to the fake serial port, like so: When you go to run anchor, use the `serial_override` ROS2 parameter to point it to the fake serial port, like so:
```bash ```bash
$ PORT_OVERRIDE=/tmp/ttyACM9 ros2 launch anchor_pkg rover.launch.py $ ros2 launch anchor_pkg rover.launch.py connector:=serial serial_override:=/tmp/ttyACM9
```
### Testing CAN
You can create a virtual CAN network by using the following commands to create and then enable it:
```bash
sudo ip link add dev vcan0 type vcan
sudo ip link set vcan0 up
```
When you go to run anchor, use the `can_override` ROS2 parameter to point it to the virtual CAN network, like so:
```bash
$ ros2 launch anchor_pkg rover.launch.py connector:=can can_override:=vcan0
```
Once you're done, you should delete the virtual network so that anchor doesn't get confused if you plug in a real CAN adapter:
```bash
$ sudo ip link delete vcan0
``` ```
