Remove unused variables from env

[mkizka]

Following the README, running npm run dev causes an error. Adding COMMON_RATE_LIMIT_MAX_REQUESTS and COMMON_RATE_LIMIT_WINDOW_MS to the .env file fixes it, but since they are not currently used, I have removed them instead.

$ npm run dev

> atproto-example-app@0.0.1 dev
> tsx watch --clear-screen=false src/index.ts | pino-pretty
