This pull request focuses on essential maintenance for the documentation site, primarily by updating the underlying Docusaurus framework and standardizing the required Node.js environment. These changes ensure the documentation platform remains current, secure, and compatible with future developments, providing a stable foundation for content delivery.

Highlights

• Node.js Version Enforcement: The project now explicitly requires Node.js version 20 or higher, enforced through a new '.nvmrc' file and updated 'engines' field in 'package.json' and 'package-lock.json'.
• Docusaurus Upgrade: Docusaurus and its related development dependencies have been upgraded from version 3.7.0 to 3.9.2, ensuring the documentation site benefits from the latest features and bug fixes.
• Docusaurus V4 Compatibility: A 'future.v4: true' flag has been added to 'docusaurus.config.js' to improve compatibility with the upcoming Docusaurus v4, preparing the project for future major updates.

Code Review

This pull request successfully updates the Docusaurus version to 3.9.2 and enforces Node.js version 20 or higher across the documentation project. The changes in package.json and package-lock.json reflect these version bumps and necessary dependency adjustments. The addition of the .nvmrc file and the future.v4 flag in docusaurus.config.js are appropriate for this upgrade.
