Date Formatting Inconsistency in "Updated" Field Tooltip

### Current Behavior There is a discrepancy in how the "Updated" field tooltip (from the `.crate-row `container) is rendered in the Svelte version compared to the original Ember.js implementation. The Svelte version currently displays a raw ISO string, whereas the original version provides a human-readable format including the local timezone. ### Expected Behavior - **Svelte Version:** Displays raw ISO 8601 string: **_2026-03-05T04:56:45.131839Z_** - **Ember.js Version:** Displays full local string: **_Thu Mar 05 2026 00:51:07 GMT-0400 (Venezuela Time)_** ### Steps To Reproduce 1. Visit https://crates.io/svelte/ 2. Navigate to "All Crates" page (/crates). 3. Hover over the "Updated" value field (from any crate row) to trigger the tooltip. ### Environment - Browser: Edge 147.0.3912.86 - OS: Windows 11 ### Anything else? _No response_
