Eto.Platform.Windows not supporting fx461

[Beyley]

Expected Behavior

Eto.Platform.Windows should be available on all frameworks that net standard 2 is available on (fx461+ and coreapp3.1+)

Actual Behavior

Eto.Platform.Windows is only available on fx462+ and coreapp3.1+

Steps to Reproduce the Problem

1. Make fx461 app
2. Import through nuget
3. Try to build

Specifications

• Version: 2.7.2
• Platform(s): WinForms
• Operating System(s): Windows 10

Unless there is a specific reason fx461 cant be supported, it should work under fx461, same with the rest of the Eto nugets (which are netstandard2), it should be as simple as bumping the framework version from fx462 -> fx461

Sorry, but .NET 4.6.1 is end of life, so it is not supported: https://devblogs.microsoft.com/dotnet/net-framework-4-5-2-4-6-4-6-1-will-reach-end-of-support-on-april-26-2022/
