AWS AMI does not support instance type m6a.4xlarge any longer.

Description

[ 1 paragraph concisely describing the bug ] I started using m6a.4xlarge instances with flatcar. I currently get the current ami via this terraform code:

data "aws_ami" "flatcar_stable_latest" {
  most_recent = true
  owners      = ["aws-marketplace"]

  filter {
    name   = "architecture"
    values = ["x86_64"]
  }

  filter {
    name   = "virtualization-type"
    values = ["hvm"]
  }

  filter {
    name   = "name"
    values = ["Flatcar-stable-*"]
  }
}

This is the subscription I need for the above generated ami: https://us-east-1.console.aws.amazon.com/marketplace/home?region=ap-south-1#/subscriptions/7b88ef15-f132-4f76-80aa-a06e68eb0117

but recently I am not able to create instances with this ami and m6a.4xlarge because they are unsupported. Any idea what has changed?

Impact

no support for common aws instance types.

Environment and steps to reproduce

go to subscription https://us-east-1.console.aws.amazon.com/marketplace/home?region=ap-south-1#/subscriptions/7b88ef15-f132-4f76-80aa-a06e68eb0117 and select provision, then try and select m6a.4xlarge

Expected behavior

new instance should work with that ami
