This PR

This pull request updates the target frameworks configuration for several projects to centralize and simplify framework management. The main change is moving the TargetFrameworks property from individual project files to the shared Directory.Build.props file, ensuring consistency across all projects. Minor formatting improvements were also made for readability.

Centralized Target Frameworks Configuration:

• Moved the TargetFrameworks property from each individual .csproj file (OpenFeature, OpenFeature.DependencyInjection, OpenFeature.Hosting, and OpenFeature.Providers.MultiProvider) to the shared Directory.Build.props file for unified management. [1] [2] [3] [4] [5]

Formatting Improvements:

• Improved formatting of Import and PackageReference elements in Directory.Build.props and OpenFeature/OpenFeature.csproj for better readability and maintainability. [1] [2]
