Accept forceRefetch in plugin list requests (#34573)

## What changed

- Add the optional `forceRefetch` boolean to `PluginListParams` and generated schemas.
- Accept both omitted and enabled values without changing `plugin/list` behavior yet.
- Cover deserialization of the enabled value in the protocol tests.
