AzureSearch Injection of SearchIndexerClient

### Is there an existing issue for this?

- [x] I have searched the existing issues

### Is your feature request related to a problem? Please describe the problem.

I am trying to create an Azure Search Configuration Job as part of the deployment, at present the **Aspire.Azure.Search.Documents** component for Aspire only supports the dependency registration of the **SearchIndexClient** and not the **SearchIndexerClient** which is required to perform some of the configuration tasks required.

### Describe the solution you'd like

I would like to use either the **SearchIndexerClient** and/or the **SearchIndexClient** from within aspire projects by using current dependency injection extension methods **AddAzureSearchClient**, **AddKeyedAzureSearchClient** or by way of new extension methods **AddAzureSearchIndexClient**, **AddKeyedAzureSearchIndexClient**, **AddAzureSearchIndexerClient**, **AddKeyedAzureSearchIndexerClient** that explicitly registers the approriate Search client. It would also be good the have the additional health check for the **SearchIndexerClient**

### Additional context

I have noticed that the **SearchIndexerClient** can be used to instantiate a **SearchIndexClient**
