Adapt the dependency-only change from closed, unmerged #7723 onto a fresh release/5.0 base (412a0c8ac6764cec1cd17df90a0293291370e4d6).

Keep Semantic Kernel at 1.71.0. Scope the supporting dependency updates to projects whose names start with Microsoft.ML.GenAI. (libraries, tests and samples).

[release/5.0] Update Semantic Kernel to 1.71.0 and required dependencies
3f6f13e 
Apply the ten dependency property updates from #7723 to the release/5.0 base. Keep MicrosoftBclMemoryVersion and the separate #7773 change unchanged.

Scope Semantic Kernel supporting dependencies to GenAI

Keep Semantic Kernel at 1.71.0 while restoring release-wide dependency versions. Apply the required AI, DI, JSON, pipelines, tensor and channel versions only to GenAI libraries, tests and samples.

Add ML.NET 5.0.1 servicing release notes (#7802)
ceb063c 
Adds concise servicing release notes for stable ML.NET **5.0.1**,
experimental packages (including DataFrame and GenAI) **0.23.1**, and
Tokenizers/data packages **2.0.1**, following the previous
servicing-note style.

Changes are derived from [v5.0.0 through candidate
a4f730e](v5.0.0...a4f730e).
The notes cover the Microsoft.Bcl.Memory dependency changes (#7773),
GenAI-scoped dependency updates (#7783), and grouped build/test
maintenance. The compatibility note explains that .NET 8+ consumers no
longer require Microsoft.Bcl.Memory through the affected packages, while
.NET Standard 2.0 builds retain the dependency at 9.0.14.

Related dependency issue: #7589.

Documentation only.

This should get later backported to `release/5.0`

## 4.0.3

# [ML.NET](http://dot.net/ml) 4.0.3

## **Bug Fixes**
- **[release/4.0] Improve unique directory generation for temp files**
([#​7528](#7528))
- Compatibility note: This change resolves a performance problem where
past versions of ML.NET would leave behind folders with the pattern
`ml_dotnet\d+` in the temp directory, which would cause model opening
performance to degrade. This fixes the problem. You may also wish to
delete these empty folders once after updating.

    Using powershell:
    ```powershell
Get-ChildItem "$env:TEMP" -Directory -Filter "ml_dotnet*" | Remove-Item
-Recurse -Force
    ```

    Using Bash:
    ```bash
    find "$TEMP" -type d -name "ml_dotnet*" -exec rm -rf {} +
    ```
    


## **Build / Test updates**
- **[release/4.0] Update dependencies from dotnet/arcade**
([#​7470](#7470))
- **[release/4.0] Use arcade script for installing MacOS dependencies**
([#​7534](#7534))

## 4.0.2

## **Enhancements**
- **[release/4.0] Support O3 OpenAI model mapping #​7395**
