parameters in new ChatMessageContent are not ordered properly

[ebCrypto]

Motivation and Context

1. Why is this change required?
   Chat Message Content are incorrect
2. What problem does it solve?
   The modelId incorrectly gets added to the ChatMessageContent.Content

Description

The constructor ChatMessageContent in Microsoft.SemanticKernel.Abstractions expects parameters like so:

 [JsonConstructor]
 public ChatMessageContent(
     AuthorRole role,
     string? content,
     string? modelId = null,
     object? innerContent = null,
     Encoding? encoding = null,
     IReadOnlyDictionary<string, object?>? metadata = null)
     : base(innerContent, modelId, metadata)

Content is expected BEFORE ModelId.
