fixes bug with matching nxos prompts (#40655)

This change addresses an issue where the prompt matching regular
expressions would not match a prompt if the hostname starts with a
numeric value.  Before this change, the connection would fail with a
socket.timeout() error.  This change updates the termnal_stdout_re
values to now check for a number.
