When Ubuntu releases a new ISO, they remove the previous URL. Unfortunately this URL is hardcoded in the packer HCL template and so the example requires frequent changes as upstream releases new minor releases.
This change takes advantage of the packer 1.8 httpdata source and allows the example to dynamically discover the checksum and URL to use. This will ensure that the example always works, and will prevent friction when new users try out this packer plugin.
Testing
[x] Ran the packer plugin and verified that it discovered the correct URL

xenserver-iso.ubuntu-2004: output will be in this color.
