Added Remix implementation of the TechEmpower Fortunes benchmark

[aaronpowell]

This builds on top of the pattern from #1866.

This is an attempt to add an implementation of the TechEmpower Fortunes benchmark in Remix. This is interesting to us given Blazor's updates in .NET 8 to support SSR, etc., and also gives another data point for a JavaScript framework that is designed around SSR.

Notes on the implementation:

• This uses the started @remix-run/server package for hosting the application, rather than any custom threading features (like Add Next.js implementation of the TechEmpower Fortunes benchmark #1866 does)
• It's using the node-postgres PostgreSQL node client with a shared pool
• When running the app locally on my development desktop (AMD Ryzen 7 3800X 8-Core), after building with npm run build and running with npm run start, with Postgres in a Docker container, and load generated by Bombardier, I see ~1,120 requests per second:

Shouldn't it go in the TechEmpower repository instead?

[DamianEdwards]

Yeah I think this is better off in TechEmpower itself than in our benchmarks repo. The PR for a Next.js implementation arguably falls into the same bucket but given Next.js' massive popularity it seems like an exception to the rule (until a Next.js implementation is added to TE itself anyway).
