[Bug] Admin CLI - resource groups documentation is wrong

### Search before asking

- [X] I searched in the [issues](https://github.com/apache/pulsar/issues) and found nothing similar.

### Version

Pulsar 2.10.3
Admin Client 3.1.0

### Minimal reproduce step
```
./pulsar-3.1.0/bin/pulsar-admin --admin-url http://platform-pulsar-broker:8080 resourcegroups update options RG_healthking_wav --byte-publish-rate 262144
```

### What did you expect to see?

Successful update

### What did you see instead?

Need to provide just 1 parameter

### Anything else?

As per https://pulsar.apache.org/reference/#/3.1.x/pulsar-admin/resourcegroups?id=update it looks like there should be an `options` parameter but that seems to be incorrect

This works (without the `options`)
```
./pulsar-3.1.0/bin/pulsar-admin --admin-url http://platform-pulsar-broker:8080 resourcegroups update RG_healthking_wav --byte-publish-rate 262144
```

I would be willing to submit a PR but I can't find the repo with the documentation.
