Summary: 데이터리안 updates bootcamp early bird deadlines

Why It Matters: The company is using a countdown to create urgency for their upcoming SQL and GA4 data analysis classes. This helps them get more students to sign up before the February 1st deadline.

What Changed:

• Updated the early bird discount countdown from D-4 to D-3 for all main bootcamps.
• Refreshed the "Popular Blog Posts" list with new articles about GA4 measurement IDs and marketing data collection.
• Reordered the recommended articles section to feature a new post about creating resume websites.
• Removed some social media links (LinkedIn, YouTube, Naver Blog) from the very bottom of the page.
