Add Encore integration guide for TypeScript SDK

[ivancernja]

Hey! 👋

I'm on the team at Encore / Encore Cloud. It's an open-source backend framework for TypeScript and Go. A lot of our users and customers use Temporal for workflows alongside Encore for their API layer and infrastructure, so I wanted to see if we could contribute an integration guide to the docs.

This PR adds a guide showing how to run a Temporal Worker inside an Encore service, define Workflows/Activities, and trigger them from type-safe Encore API endpoints. I've covered local dev and production deployment.

I placed it under TypeScript SDK > Integrations alongside the AI SDK guide, and renamed the index page from "AI integrations" to just "Integrations" since it's no longer AI-specific. Happy to adapt the placement or rename things if you'd prefer a different structure, just let me know!

Also happy to add a Go SDK equivalent if you're interested.

Changes

• docs/develop/typescript/integrations/encore.mdx - new integration guide
• docs/develop/typescript/integrations/index.mdx - updated title and added Encore to the list
• sidebars.js - added Encore to the TypeScript Integrations sidebar

Hi, Ivan, and thanks very much for your interest in Temporal documentation! We're currently working on a framework for accepting integration contributions, so we're going to have to defer this submission for now, but we'll publicly post our submission process once it's ready.
