Description of problem:

As noted in https://github.com/redhat-developer/red-hat-developers-documentation-rhdh/pull/257 I'm seeing more unrendered attributes in the code snippets, like `{product-chart-version}` instead of `1.3`. For example this:

\[source,terminal]
----
podman push --remove-signatures registry.redhat.io/rhdh/rhdh-hub-rhel9:\{product-chart-version}
default-route-openshift-image-registry.<hostname>/<project_name>/rhdh-hub-rhel9:\{product-chart-version}
----

should have the `subs="attributes+"` declaration:

\[source,terminal,subs="attributes+"]

Task here is to look through all the 1.2 or 1.3 user docs and look for places where an attribute appears in the code snippet instead of being replaced by its value.

List of attributes:
https://github.com/redhat-developer/red-hat-developers-documentation-rhdh/blob/main/artifacts/attributes.adoc#L15

Another approach could be to

• add

  ,subs="attributes+"]

  to ALL code blocks

• add a grep check in the build.sh (and/or build-ccutil.sh) that will fail if any

  [source]

  blocks are found which do NOT declare the

  subs="attributres+"

  rendering instruction.

Of course if we're moving away from .adoc and over to some new Adobe DITA XML format, this might be moot.
