STRIPE_DEVICE_NAME env var not used

[louismariegaborit]

Issue

The STRIPE_DEVICE_NAME env var seems not used at login action.

Steps to reproduce

docker run -it --rm -v $PWD/configStripe.toml:/root/.config/stripe/config.toml -e STRIPE_DEVICE_NAME=teststripe stripe/stripe-cli login
The value of device_name in the configStripe.toml created by the command is not the STRIPE_DEVICE_NAME value.
And therefore, the value on the Stripe dashboard is not correct also.

Environment

Docker on Ubuntu
