Trying to implement gcp-wif with GHA, seems there may be a mistake in the docs - https://atmos.tools/cli/configuration/auth/providers#workload-identity-federation I see this error in GH

**Error:** parse gcp/wif spec: invalid provider config invalid auth config: spec is nil
# Initialize Providers
**Error:** failed to initialize providers: invalid provider config: provider=gcp-wif: parse gcp/wif spec: invalid provider config invalid auth config: spec is nil

Seems as though the configuration should look like this?

auth:
  providers:
    gcp-wif:
      kind: gcp/workload-identity-federation
      spec:
        project_id: my-gcp-project
        project_number: "123456789012"
        workload_identity_pool_id: github-pool
        workload_identity_provider_id: github-provider
        service_account_email: <mailto:ci-sa@my-project.iam.gserviceaccount.com|ci-sa@my-project.iam.gserviceaccount.com>

correct, spec is missing indeed, feel free to open PR with the fix for that
