docs: Update README badges and improve documentation formatting

[RedStar071]

Summary

Updated the README.md file to improve badge consistency, add descriptive labels, and enhance overall documentation formatting.

Key Changes

• Badge Provider Migration: Migrated all shield badges from img.shields.io to shieldcn.dev with the variant=branded parameter for consistent styling
• Improved Badge Labels: Added descriptive text labels to all badge references (e.g., "GitHub latest release badge", "Discord community badge") for better clarity
• Badge Updates:
  • Replaced "GitHub release date" badge with "GitHub last commit" badge for more relevant information
  • Updated badge URLs to use the new provider's endpoints
• Formatting Improvements:
  • Changed "Share WolfStar Repository" from bold text to a proper heading (### level)
  • Added descriptive text to the "back to top" link for better accessibility
• Reference Link Updates: Updated all badge reference definitions in the links section to point to the new badge provider URLs

Notable Details

• All badge functionality remains the same; only the visual provider and styling have been updated
• The new badge provider (shieldcn.dev) appears to offer consistent branded styling across all badges
• Documentation clarity is improved through explicit badge descriptions in alt text
