Missing 'npm: xml2js@ 0.6.2' Node Module during github action execution

Start by rerunning the shown GitHub Actions workflow and inspecting the Deno command's dependency-resolution error for npm: xml2js@0.6.2. Trace how the jsr:@goog/flow-lens invocation loads that module; the work is done when Generate flow diagrams completes successfully in the pull-request workflow.
