Use the EKS default Kubernetes version when --version is not set - #8905

DescribeClusterVersions already reports which version EKS treats as the default, but create cluster ignored it and always used the hardcoded api.DefaultVersion. eksctl now takes the default version only from DescribeClusterVersions: api.DefaultVersion is removed and NewClusterConfig no longer seeds metadata.version, so both the flag path and config files without metadata.version resolve to the EKS default. If EKS does not flag a default, create cluster without a version, --version auto and create nodegroup --version=default fail and ask for an explicit version. Other commands that go through NewCtl, such as get cluster, utils describe-cluster-versions, utils describe-addon-versions and the delete cluster --force fallback, keep working. utils migrate-to-pod-identity now looks up the pod identity agent addon for the cluster's version instead of the previously seeded default. The integration tests' -eksctl.version flag now defaults to the EKS default version, resolved without panicking when it cannot be looked up. Signed-off-by: Nathan Clonts <nclonts@amazon.com>

Description
create clusternow defaults to the version EKS flags as default inDescribeClusterVersions, instead of the hardcodedapi.DefaultVersion(1.34), which is removed. No more PRs like #8645 to bump the default.If EKS flags no default,
create clusterasks for an explicit--version.Tested in us-west-2:
create clusterwith flags and with-f, both without a version, came up on 1.36 (the current EKS default).Checklist
