Allow passing `JsonSerializerContext` to Ollama

[dealloc]

Related to an existing integration?

Yes

Existing integration

CommunityToolkit.Aspire.OllamaSharp

Overview

OllamaSharp's client is AOT compatible if you pass in a JsonSerializerContext with the type information.

However, Aspire's integration does not allow passing this field in making it impossible to use this package in an AOT environment.

Usage example

builder.AddKeyedOllamaApiClient("embedding", settings => settings.JsonSerializerContext = MySerializerContext.Default)
	.AddEmbeddingGenerator();

basically add in the option to pass the JsonSerializerContext

Breaking change?

No

Alternatives

currently no alternatives exist to make AOT possible
