.github/workflows/resource-counts.yml:          datasources=$(terraform providers schema -json | jq '.provider_schemas[] .data_source_schemas | length')
.github/workflows/resource-counts.yml:          resources=$(terraform providers schema -json | jq '.provider_schemas[] .resource_schemas | length')

It looks like the Resource Counts workflow also needs setup-terraform.
