Enhancement: Moving website to a different host

[estruyf]

Due to Vercel's change in support for open-source projects, we will move the website and documentation to a different host.

• Convert Next.js APIs to Azure Functions
• Create a new OpenGraph API
• Moving APIs to Azure Functions
• Configure CDN
• Update links in the extension
• Update API calls in the DOCs to the new API location
• Moving docs to Netlify /Cloudflare/Azure

Most APIs have been converted to Azure Functions, code is available here: https://github.com/FrontMatter/frontmatter-fncs

Currently testing out Cloudflare Pages as the option to move the documentation.

I moved the docs over to Netlify, but I found one issue with the beta docs. Netlify doesn't seem to support setting custom domains for specific branches.

The branch name becomes the subdomain. For example: dev becomes dev.frontmatter.codes.
