Let me know if you need me to run additional commands to test this.

Issue looks like it is in internal/aws/console/console.go and needs some logic when it is a govcloud account/region.

const signinURI = "https://signin.aws.amazon.com/federation"
...
const consoleURI = "https://console.aws.amazon.com"

needs to be

const signinURI = "https://signin.amazonaws-us-gov.com/federation"
...
const consoleURI = "https://console.amazonaws-us-gov.com"

Rain version that I tested

rain --version
Rain v1.7.5 linux/amd64

Debug output

rain --profile gov-sandbox console --region us-gov-east-1 --debug
