Expand Join Our Community section with all platform links

[SaharPak]

Problem

The Community section (CommunitySection.tsx) currently only shows two cards: Telegram Group and YouTube. We need to include all our platforms so people can follow us wherever they prefer.

Goal

Expand the section to include cards/links for all Tech Immigrants platforms:

1. Telegram Channel (7,100+ subscribers) — https://t.me/techimmigrantschannel
2. Telegram Group (17,000+ members) — https://t.me/techimmigrants
3. YouTube (190+ episodes) — https://youtube.com/@techimmigrants
4. LinkedIn — https://linkedin.com/in/saharpak
5. X / Twitter — https://x.com/saharlead
6. GitHub — https://github.com/TechImmigrants

Suggested Approach

1. Redesign the grid from 2 columns to a responsive layout that fits 5-6 platforms.
   • Option A: Keep the large card design but use a 3-column grid
   • Option B: Use smaller, icon-focused cards (icon + platform name + follower count + join button)
   • Option C: A mix — 2 featured cards (Telegram + YouTube) on top, smaller cards below for the rest
2. Each card should have:
   • Platform icon (use lucide icons or custom SVGs for Telegram/X)
   • Platform name
   • A relevant stat (member count, subscriber count, episode count)
   • A CTA button ("Join" / "Follow" / "Subscribe")
   • Link opens in a new tab
3. Update the member counts to current numbers (see above).
