logging_writer grant to Trigger SA may be duplicated

[rolandostar]

google_service_account.trigger_sa.email might have redundant grants in the terraform modules

In infra/modules/firebase-hosting-service/main.tf#L53-L58:

# 5. Give the trigger SA permission to write logs
resource "google_project_iam_member" "logging_writer" {
  project = var.gcp_project_id
  role    = "roles/logging.logWriter"
  member  = "serviceAccount:${google_service_account.trigger_sa.email}"
}

And in infra/modules/cloud-run-service/main.tf:

resource "google_project_iam_member" "logging_writer_binding" {
  project = var.gcp_project_id
  role    = "roles/logging.logWriter"
  member  = "serviceAccount:${google_service_account.trigger_sa.email}"
}

Since google_project_iam_member is non-authoritative this should be safe but Terraform will still track both entries in the state, flagging to verify whether it's intended or not.
