Official SvelteKit Demo Request

[arkmech]

Would like an Official SvelteKit demo.

1. In, svelte.config.js, using @sveltejs/adapter-node as adapter.
2. Run vite build, generates build directory with SvelteKit handlers
3. @t3-oss/env-core ./src/env.ts, where createEnv is setup.
4. Two places use env.ts: ./src/lib/server/index.ts(express server) and./src/lib/server/payload/payload.config.ts`,
5. Run using cross-env PAYLOAD_CONFIG_PATH=./src/payload.config.ts tsx watch ./src/lib/server/index.ts
