Prevent creating the login credential for IAM bot account

[longnd]

Why

An IAM service/bot account is created as part of the IAM module. It will be used to provision the changes to the AWS infrastructure, e.g. through Terraform.
Currently the bot account is created with login credential

infrastructure-templates/src/generators/addons/aws/modules/core/iamUserAndGroup.ts

Lines 88 to 91 in 12ebedf

	output "iam_bot_temporary_passwords" {
	description = "List of first time passwords for bot accounts. Must be changed at first time login and will no longer be valid."
	value = module.iam_bot_users.temporary_passwords
	}`;

It is unnecessary and exposes more risk. We should limit the creation of the account without console access (no login credential)
