[Bug] "Failed computing delta" for `deregistration_delay` and `keepers`

I hit some errors when running aws openshift-snc create --spot.

Specifically:

• [rawstate] Failed computing delta at "keepers" for pv={<nil>} and v=tftypes.Map[tftypes.String]<null> and
• [rawstate] Failed computing delta at "deregistration_delay" for pv={300} and v=cty.StringVal("300"): no efficient delta for type cty.String (for main-aos-tg-22, main-aos-tg-443, and main-aos-tg-6443.

I assume this is causing the additional error I see: (main-ocp-readiness-aos-cmd): error: wait: remote command exited without exit status or exit signal: running "while [ ! -f /tmp/.crc-cluster-ready ]; do sleep 5; done".

Although there are no "Outputs" at the end, and no kubeconfig is saved locally, the cluster appears to be provisioned and I can at least SSH to the host.

Using:

• both mapt:v1.0.0-dev and mapt:v0.9.9 images
• --arch x86_64
• --version 4.20.1

Start with the aws openshift-snc create --spot entry point and reproduce the failure using the reported architecture, OpenShift version, and image versions. Trace the deregistration_delay, keepers, and main-ocp-readiness-aos-cmd diagnostics to determine whether the reported errors prevent completion; done means the command finishes successfully and saves the kubeconfig without the two resource errors.
