Poem

🐇✨ The cache moves fast, from v2 to v4,
A hop and a skip, couldn't ask for more!
The workflow stays strong, the pages still flow,
Just newer and swifter—away we go! 🚀

23-67: Optional: Audit other action versions for consistency.

While this PR correctly bumps the cache action, other actions in the workflow are using older versions (e.g., actions/setup-node@v2, actions/upload-pages-artifact@v1). Consider performing a broader audit and update of all GitHub Actions to their latest stable versions for consistency and to avoid similar deprecation issues in the future.

39-45: Necessary version bump—v2 is now retired.

Starting February 1st, 2025, actions/cache v1-v2 were closed down, and workflows calling retired versions after March 1st, 2025 fail. Given the current date and workflow status, this bump is essential. Changes are fully backward compatible, and the key, path, and restore-keys configuration syntax remain unchanged.
