Updates the source_image_family in the example build.
Note, the previous Packer release version 1.8.1 included fixes to address issues with legacy SSH key algorithms that fundamentally arose due to upstream changes in OpenSSH. This typically manifested in the form of build failures due to Packer authentication errors (handshake failed) on contemporary OS base images. Client authentication support for algorithms based on SHA-2 for use with existing RSA keys is now implemented, which will mitigate this particular corner case.
