fix: Display year for releases from previous years on website (#13276) (#13291)

### 🐛 Bug Fix

**Fixes #13276 - Website does not show year of releases**

### 📝 Description

Fixed the Twenty website to properly display release years for previous
year releases and standardized date formatting.

**Key Changes:**
- Show year for releases from previous years
- Abbreviate month names for consistent layout (e.g., "April" → "Apr")
- Added fallback to prevent runtime errors when no releases exist

### 🔧 Files Changed

- **`formatDisplayDate.ts` (new)** - Utility function for consistent
date formatting
- **`Release.tsx`** - Use utility function and improve CSS layout
- **`page.tsx`** - Add fallback for undefined `latestGithubRelease`

### 🧪 Example Output

| Before | After |
|--------|-------|
| `April 25th 2024` (missing year) | `Apr 25th 2024` |
| `April 25th 2025` | `Apr 25th` |
| Runtime error | Graceful fallback |
