.env variables are being read in production, documentation says they are not

[Antoine-lb]

Describe the bug

The documentation states "[in adapter-node] In production, .env files are not automatically loaded.", but variables that start with VITE_, PUBLIC_ and SECRET_ are being loaded without dotenv.

The fix would be to update the documentation to avoid surprises.

note: I think this is the reason of why so many people struggle with the ORIGIN env var, this makes it hard to debug

Reproduction

(there most be a simpler but I don't know how to print all the variables)

1. Add SECRET_API_KEY and BODY_SIZE_LIMIT=Infinity variable in a .env result: SECRET_API_KEY is available but I get hit with Payload Too Large

2. Add BODY_SIZE_LIMIT=Infinity in the CLI before the production build my production cmd: BODY_SIZE_LIMIT=Infinity pm2 start node --name="prod" -- ./build/index.js result: everything works

Logs
