Conversation
Not all AWS regions support gp3 and this hardcoded value breaks IPI installs to those regions.

PR #5239 switched the default EBS volume type from gp2 to gp3. But in doing so, this breaks support for AWS regions which do not have gp3 (e.g. us-iso-east-1, us-isob-east-1). While it's possible to set the EBS volume type in the install-config for control plane and compute nodes, the bootstrap instance is hardcoded in the terraform.
Since the bootstrap instance is a short lived instance, doesn't require large amounts of iops, and will be destroyed after cluster bootstrapping, switch it back to gp2.
