Allow Dash Operation Naming Strategy

When you use the dash operation naming strategy, react-admin fails to properly inflect the resource name into a nicely formatted name.

if the resource name is `air-door-event`, react admin will format it as `Air-door-event`.

I've been able to customize the menu links using this following snippet when formatting the name:

```
inflection.titleize(inflection.humanize(inflection.pluralize(name).replace(/-/g, "_")));
```

Curious if this is something we should add as a cookbook doc so that people can optionally customize, or if api-platform/admin should just override the layout/menu to use the above instead of their default inflection.
