[Question] Why are some configuration keys changed to snake_case while others are still camelCase?

### Release version

v7.0.0-alpha.3.0.0

### Question Details

Since v7alpha3 _some_ configuration keys use snake_case, like named_values, service_policies, version_sets. However many keys still use camelCase, like apimServiceName, displayName, loggerId etc.

Why are some snake_case and others still camelCase? I find this personally super confusing and inconsistent.

For example below the new [configuration.extractor.yaml](https://github.com/Azure/apiops/blob/v7/configuration.extractor.yaml) example, why is workspaceName1 camelCase and then further below named_values is snake_case? To me this seems strange to mix naming conventions like this.

```yaml
workspaces:
- workspaceName1:
apis:
- workspaceApiName1:
operations: []
diagnostics: []
schemas: []
releases:
- workspaceReleaseName1
backends:
- workspaceBackendName1
diagnostics: []
groups: []
loggers:
- workspaceLoggerName1
named_values:
- workspaceNamedValueName1
policy_fragments:
- workspacePolicyFragmentName1
products:
- workspaceProductName1
subscriptions: []
tags:
- workspaceTagName1
version_sets:
- workspaceVersionSetName1
```

### Expected behavior

Either all keys should use camelCase as it previous was or all keys should use snake_case.

### Actual behavior

Some keys are camelCase, some are snake_case.

### Reproduction Steps

None

Start with the linked configuration.extractor.yaml example and compare its key naming with the v7alpha3 configuration rules. Trace where the example or configuration schema is documented or generated; done means the naming convention and the reason for any mixed keys are made consistent or clearly documented.
