.Net: Fixes for Chroma connector to be compatible with Chroma 0.4.10

[dmytrostruk]

Motivation and Context

Resolves: #2790

This PR contains changes to update processing of boolean values in order to be compatible with Chroma 0.4.10.
With new Chroma updates we need to update Chroma connector on regular basis to be compatible.

The note has been added to Chroma notebook and README file to show the latest version of Chroma, which was used to verify the connector.

In order to fix notebook to be compatible with latest version, the notebook should be updated as soon as this PR is released.

Description

1. Removed ChromaBooleanConverter to be compatible with Chroma 0.4.10.
2. Added note with latest tested version of Chroma in notebook and README file.
3. Updated unit tests.

Contribution Checklist

• The code builds clean without any errors or warnings
• The PR follows the SK Contribution Guidelines and the pre-submission formatting script raises no violations
• All unit tests pass, and I have added new tests where possible
• I didn't break anyone 😄

I still get this error downloading main semantic-kernel and main chroma and executing the 09 tutorial notebook in C#.

It can write data into Chroma, and query them, looks like it fails to deserialize:

Error: Microsoft.SemanticKernel.Diagnostics.SKException: Function `recall` execution failed. System.Text.Json.JsonException: The JSON value could not be converted to Microsoft.SemanticKernel.Memory.MemoryRecordMetadata. Path: $.is_reference | LineNumber: 0 | BytePositionInLine: 102.

@jamescarter-le Thanks for reporting. As mentioned in notebook, current version of SK in notebook is compatible with Chroma version 0.4.0 at the moment and not above. We plan to upgrade SK version in all notebook examples soon, and after that it will be compatible with latest Chroma version. Meanwhile, you can test using Example15_TextMemoryPlugin example, which should be compatible with latest Chroma version:

semantic-kernel/dotnet/samples/KernelSyntaxExamples/Example15_TextMemoryPlugin.cs

Lines 54 to 55 in 11fdd43

	// Chroma Memory Store
	// store = CreateSampleChromaMemoryStore();

Oh I see! The notebook is referencing a nuget package whilst the KernelSyntaxExamples reference the latest code and project.

I was able to run the same by pulling 0.4.0 chroma, my fault for not reading the notebook thoroughly.

Could change the chroma download instructions to include:

git fetch --all --tags
git checkout tags/0.4.0 -b sk-notebooks

Appreciate the support and enjoying SK so far.
