Migrate from GitHub Pages to Vercel

[CorreyL]

@SamHuo213 has mentioned that while deploying a NextJS app to GitHub Pages has worked and is possible, it is not ideal.

Vercel's free tier appears to be generous enough that hosting of the OpenBC website to Vercel should be feasible.

Potential tasks include:

• Adjusting GitHub Actions to deploy to Vercel
• Have the GitHub Pages & Vercel deployment run simultaneously, just to make sure the Vercel deployment works as expected, then eventually deprecate & delete the GitHub Pages deployment

@SamHuo213 @tokifyi In order to continue with this ticket, a request has been sent for permission to install Vercel as an app in the OpenBCca org

Some notes after permitting Vercel access to the OpenBCca website repo:

• Looks like creating a Team on Vercel will require payments eventually 🥲

• Possible configurations on Vercel to the deployment:

• First deployment out of the box, it'll definitely need more configurations to get it to display properly though:
