stanford-murine: point the data card at this repository

Syncs the stanford-murine card on the Hub with the reviewed state on GitHub (open-h/OpenH-RF).

One correction: the card pointed readers at `openh-rf/stanford`, a staging repo, for the converted data. It now points at `nvidia/OpenH-RF/stanford-murine` — this folder. Nothing else changed.

Files changed: 1.
