This is because the upstream provider has a unexpected module name of terraform-provider-meraki without the github.com/<org> part. Our parsing does not expect that and fails.

We should probably stop panic'ing and give a user-friendly error.

Relatedly, how do I fix this for this specific provider? Specify upstream-provider-org: cisco-open somewhere in ci-mgmt?
