💡 Feature Request: Add .ease-hover-underline-reveal Component

Is your feature request related to a problem?
While the repository has general hover styles, it doesn't currently include a smooth text-link underline animation common in modern navigation bars.

Describe the solution you'd like
I'd like to submit a clean example layout under submissions/examples/hover-underline-reveal/ that creates a text link hover state. When hovered, the underline grows outward smoothly from the center.

Implementation
This will live entirely inside its own sandbox folder with standalone demo.html, style.css, and README.md files, so it won't affect any core files or cause merge conflicts.

I'd love to take this on. Please assign this issue to me!

Hi @SAPTARSHI-coder, my PR was successfully merged, but I accidentally clicked 'unassign' on the Pull Request page yesterday. Because of this, my GSSoC leaderboard points dropped today. Could you please re-assign me as the assignee on this PR so the leaderboard can sync up my points again? Thank you so much!

Dear @SAPTARSHI-coder,
Hope you are doing well! My Pull Request was successfully merged, but I noticed today that my GSSoC leaderboard points have dropped. I am not completely sure of the exact reason, but I did accidentally click 'unassign' on the PR page yesterday, so I am wondering if that might have caused the system sync issue.
