[BUG] `GetInputItems` is duplicated in `OpenAIResponseClient`

[joseharriaga]

Describe the bug

OpenAIResponseClient has the following methods:

public virtual CollectionResult<ResponseItem> GetInputItems(string responseId, ResponseItemCollectionOptions options = null, CancellationToken cancellationToken = default);
public virtual CollectionResult GetInputItems(string responseId, int? limit, string order, string after, string before, RequestOptions options);
public virtual AsyncCollectionResult<ResponseItem> GetInputItemsAsync(string responseId, ResponseItemCollectionOptions options = null, CancellationToken cancellationToken = default);
public virtual AsyncCollectionResult GetInputItemsAsync(string responseId, int? limit, string order, string after, string before, RequestOptions options);

But it also has the following methods:

public virtual CollectionResult<ResponseItem> GetResponseInputItems(string responseId, ResponseItemCollectionOptions options = null, CancellationToken cancellationToken = default);
public virtual CollectionResult GetResponseInputItems(string responseId, int? limit, string order, string after, string before, RequestOptions options = null);
public virtual AsyncCollectionResult<ResponseItem> GetResponseInputItemsAsync(string responseId, ResponseItemCollectionOptions options = null, CancellationToken cancellationToken = default);
public virtual AsyncCollectionResult GetResponseInputItemsAsync(string responseId, int? limit, string order, string after, string before, RequestOptions options = null);

I suspect they were accidentally duplicated when during the pagination overhaul.
