Correct ssh-copy-id command syntax

The ssh-copy-id command syntax in sdk-ade-remote-debugging.yaml is incorrect in two ways:

• The user is in capitals, whilst the actual username used should be in lower case
• The test case uses $HOST as a convention for the hostname/IP to be used for the target device, this command is missing the dollar sign.
