Change SSH username to nano@nano

[jjaime2]

Description

When attempting to run ada_feeding software on the real robot and with a device other than lovelace via python3 src/ada_feeding/start.py, the feeding screen session will attempt to connect to the Jetson Nano via ssh using the username nano. By default, this username will be expanded to include the system's username, e.g. for my device it expands to regulus@nano which does not exist. This PR addresses this issue by specifying the complete username to connect to as nano@nano.

Testing procedure

• Launch the code in real
• Connect to the camera screen session via screen -r camera
• Verify that the command ssh nano@nano -t ./start_nano.sh is ran and providing the Jetson Nano SSH password connects successfully
• Verify that the RealSense node launches successfully
