Problems with the main source content in English and the translations.

Issue Description:

There are some problems with the main source content in English and the translations.
The list below explains these problems.

Issues

1. Each one of the translations in [https://github.com/microsoft/Generative-AI-for-beginners-dotnet/tree/main/translations] does not match the main readme [https://github.com/microsoft/Generative-AI-for-beginners-dotnet/blob/main/README.md] at the top of this repository. In example: the translations does not include the "What's new" section.

Translate and update each one of the translations to match the content of the main readme.

2. Each one of the translations does not include the folder '10-WhatsNew' [https://github.com/microsoft/Generative-AI-for-beginners-dotnet/tree/main/10-WhatsNew] at the root of the repo. Add this folder with the content translated to each language.

3. Apply the same criteria and process to all the markdown files that represent documentation that are part of the repository and not part of the [translations] folder.

4. Once the translations are done, update the translation table [https://github.com/microsoft/Generative-AI-for-beginners-dotnet/blob/main/README.md#-multi-language-support] with the date of the last update
