Update .NET versions and project configurations

- Set `NetCurrent` to `net9.0` and `NetMinimum` to `net8.0` in `Directory.Build.props`.
- Updated SDK version in `global.json` to `9.0.202`.
- Changed target frameworks in `coverlet.collector.csproj`, `coverlet.console.csproj`, `coverlet.core.csproj`, and `coverlet.msbuild.tasks.csproj` to support multiple frameworks.
- Modified `CoverletToolsPath` in `Directory.Build.targets` to include `netstandard2.0`.
- Updated coverage file naming in `Msbuild.cs` to reflect the build target framework.
