[DevOps]: create a Docker image version on NemoClaw per version of OpenClaw

Review PR #55 and the current NemoClaw image build first; use npm view openclaw versions --json to understand the version source. Define the recurring repository workflow so each available OpenClaw version produces a NemoClaw image with an OpenClaw-version tag, and verify the optional dual-tag behavior if adopted.

@johntmyers : this is a continuation of https://github.com/NVIDIA/OpenShell-Community/pull/55 based on your remrark.

Currently, NemoClaw image defines and uses 1 single OpenClaw version in its buzild. Frequent updates would be needed to keep it up to date as OpenClaw evolves very fast.

A much better approach is to build one version of the NemoClaw image for OpenClaw for each OpenClaw version. The list of available OpenClaw packages is easy to obtain via the command below

So, it would be good to let the user choose the version of OpenClaw that he wants by having 1 image available for each of those versions.

Consequently, there should be a workflow in this repo running regurlary and creating new versions of NemoClaw when new versions of OpenClaw get publshed. Those images would be tagged ith the version of OpenClaw.

Optionally, those images could have a dual tag + as NemoClaw also gets updated to offer choices in the 2 dimensions

npm view openclaw versions --json
