Set public = t for server.cpu_profile cluster settings

The setting below needs to be documented according to [DOC-8144](https://cockroachlabs.atlassian.net/browse/DOC-8144):

```
server.cpu_profile.cpu_usage_combined_threshold
server.cpu_profile.total_dump_size_limit
server.cpu_profile.interval
server.cpu_profile.duration
server.cpu_profile.enabled
```

However they are not publicly documented on [the cluster settings page](https://www.cockroachlabs.com/docs/v23.1/cluster-settings) because they have `public = f` in `crdb_internal.cluster_settings`. The cluster settings page is automatically generated with settings where `public = t`.

Describe the solution you'd like
Please set public = t for the above cluster settings.
