feat: use relative-time element for PR timestamp localization

[Paveltarno]

Summary

Implements timestamp localization for auto-generated PR descriptions using GitHub's <relative-time> web component. This replaces the static UTC timestamps with dynamically localized times that automatically adjust to each viewer's timezone.

Changes Made

• Updated .github/workflows/pr-description.yml line 81
• Changed timestamp instruction from YYYY-MM-DD HH:MM UTC format to ISO 8601 format (YYYY-MM-DDTHH:MM:SSZ)
• Wrapped timestamp placeholder in <relative-time datetime="..."></relative-time> HTML element

Benefits

• ✨ Automatic timezone localization for all viewers
• 🕐 Shows relative time ("2 hours ago", "just now", etc.)
• 🖱️ Hover displays exact localized datetime
• 🌍 Better UX for global teams
• 🚀 No backend logic needed - handled client-side by GitHub

Example Output

What viewers will see:

• "2 hours ago" (or "just now", "5 minutes ago", etc.)

On hover:

• Exact time in their local timezone (e.g., "Feb 2, 2026, 3:49 AM PST")

Testing

Next PR that triggers the auto-description workflow will use this new format. The <relative-time> element is a standard GitHub web component that works across PR descriptions, comments, and issues.
