### Steps to Reproduce

<!--- Paste example playbooks or commands between quotes below -->
```yaml (paste below)
        - name: "Create consul agents token"  # noqa: run-once[task] no-handler
          run_once: true
          delegate_to: localhost
          block:
            - name: "Create consul agent policy"
              community.general.consul_policy:
                host: "192.168.1.100"
                token: "b9af57a6-2553-4e85-a2cd-5e647332b5c5"
                port: 8500
                scheme: http
                state: present
                name: agents-policy
                rules: |
                  agent_prefix "" {
                       policy = "write"
                   }
                   node_prefix "" {
                        policy = "write"
                    }
                    service_prefix "" {
                      policy = "read"
                    }
              register: _consul_agent_policy

            - name: "Create consul agents token"
              community.general.consul_token:
                host: "192.168.1.100"
                token: "b9af57a6-2553-4e85-a2cd-5e647332b5c5"
                port: 8500
                scheme: http
                state: present
                local: true
                policies:
                  - id: _consul_agent_policy.policy.ID
              register: _consul_agent_token
```
This will raise a runtime error while trying to create the token

### Expected Results

The token module should create the token.
