Frontity Node 18 Upgrade

I need an experienced developer to upgrade our Frontity project to be compatible with Node 18 so that we can update the local repository to use the new upgraded Frontity repo and deploy it on Vercel.

Here is the issue on the Frontity forum https://community.frontity.org/t/potential-upcoming-issue-with-vercel/6946/1

Tasks:
- Fork the Frontity repository for an independent version.
- Upgrade to support Node 18, fixing webpack and OpenSSL compatibility issues.

Ideal skills:
- Proficiency in Node.js and React.js
- Experience with source control
- Familiarity with Vercel deployments
