thermal: intel: int340x: Add new line for UUID display

Prior to the commit "763bd29fd3d1 ("thermal: int340x_thermal: Use
sysfs_emit_at() instead of scnprintf()", there was a new line after each
UUID string.

With the newline removed, existing user space like "thermald" fails to
compare each supported UUID as it is using getline() to read UUID and
apply correct thermal table.

To avoid breaking existing user space, add newline after each UUID string.
