3-3: Clear branding update with proper formatting.

The package name reference uses backticks to denote the scoped package name (@openhax/codex), and the added clarification—"the OpenHax Codex OAuth plugin"—maintains context for readers unfamiliar with the new branding. The phrasing is consistent with how package documentation typically refers to ownership and identity.
