The Quickstart command in the README contains unnecessary whitespace characters, causing the command to fail.

INVALID_ARGUMENT error occurs as follows with device ID

gcloud iot devices create atest-dev  --region=us-central1 \
    --registry=atest-registry \
    --public-key path=ec_public.pem,type=es256

ERROR: (gcloud.iot.devices.create) INVALID_ARGUMENT: The format of 'device.id' is invalid:'atest-dev '

and region.
This command is executed by removing whitespace characters from the device ID.

gcloud iot devices create atest-dev --region=us-central1 \
    --registry=atest-registry \
    --public-key path=ec_public.pem,type=es256

ERROR: (gcloud.iot.devices.create) NOT_FOUND: The cloud region 'projects/*******' (location 'us-central1 ') isn't supported. Valid regions: {asia-east1,europe-west1,us-central1}

I am using the following environment.

gcloud --version

Google Cloud SDK 367.0.0
bq 2.0.72
core 2021.12.10
gsutil 5.5
