Adding Remix documentation

[NCHitsman]

Adding Remix documentation. Because Remix is mainly built off of React the implementation is fairly straight forward. Using the already built Browser package, we can mirror the implementation. I also added an extra section for Route Tracking based on the requests made in this issue (https://github.com/hyperdxio/hyperdx/issues/68). It is also worth noting that Remix can use one of many backends (Express, Cloudflare Workers, Netlify, Vercel, Fastly, AWS, Deno, Azure, Fastify, Firebase, etc.). To this end I linked the Node.js documentation for use in Node.js servers.

I made sure to test this using the tutorial Remix project and cloud HyperDX.
