Make EntityFrameworkCore.Jet available on `net6.0`

By using `[SupportedOSPlatform("windows")]` at assembly level instead of targeting `net6.0-windows`.

This will enable taking a dependency on the EntityFrameworkCore.Jet* NuGet packages on Linux and macOS. The consumer of EntityFrameworkCore.Jet can then decide how to handle [CA1416][1] either by adding `[SupportedOSPlatform("windows")]`, by targeting `net6.0-windows` or by testing `OperatingSystem.IsWindows()` at runtime.
