rack service_timeout only in production

According to the rack timout documentation
https://github.com/zombocom/rack-timeout/blob/main/doc/settings.md#service-timeout

"Service timeout can be disabled entirely by setting the property to 0
or false"

Limiting the service timeout to be active only in production enables debugging in dev and test env
without fearing for the timeout to take oneself out of context.
