DOC-14254 expandHeaderLevels in playbook site.keys.navGroups

Instead of having to configure `:page-nav-header-levels:` in every antora.yml, we can just update in the playbook

```
site:
  keys:
    navGroups:
       [
         { "title": "Capella", "startPage": "home::cloud.adoc", "components": ["cloud", "app-services", "ai", "analytics"], "expandHeaderLevels": 1 },
         ...
         { "title": "Develop", "startPage": "home::developer.adoc",
             "expandHeaderLevels": 1,
             "subGroups": [
               {
                 "title": "Operational SDKs",
        ...
```
