Use latest plugin version in deployment examples

Using a specific version of the plugin in
deployment examples requires updating it
for each release. This poses a risk of users
deploying an older version of the plugin than the
specific one they checked out.

The proposal is to always use `latest` and then in
every release, update yaml for the release and
upload it to the release page.
