Additional information

Simple Fix.

Check https://registry.npmjs.org/pnpm for valid matching version before creating http request.

Reproduce the issue with package.json and the listed corepack and pnpm commands, then trace the Corepack path that handles the requested package-manager version and the HTTP 404. Done means invalid versions produce a specific, helpful validation error instead of an unhandled ambiguous response.
