WIP: Adding Accessibility doc for Core WinForms

[M-Lipin]

Summary

Adding Accessibility doc for Core WinForms which describes the changes made in WinForms accessibility in comparison with .NET Framework 4.8 https://github.com/microsoft/dotnet/tree/master/Documentation/compatibility

https://github.com/microsoft/dotnet/blob/master/Documentation/compatibility/winforms-accessibility-changes-48.md

Fixes #13870

[rpetrusha]

There's not really a home for this article right now. Ultimately, it will have to go in the .NET Core Guide. I've created #13893 to do that.

I've left a number of comments, @M-Lipin. This article more closely needs to resemble What's new in accessibility in .NET Framework than the old compatibility items in the Microsoft/dotnet repo. I'll do another review once these changes are made.

It could be a good idea to wrap control names into `, e.g. ...`ListBox` control...

@M-Lipin Hello. There are a few changes you should accept as suggested by Ron. Also, we have a linter running to ensure that the markdown content we accept is well formed. Can you please address those? If you're using VSCode you should be getting the linter rules if you open the repo root. Also, you can see the lint results in the Checks tab at the top.

@M-Lipin Hello. Sorry about losing sight of this pull request over the holiday season. We had previously implemented a linter to ensure we have constant structure in the markdown used. There are a few changes that need to happen. Would you prefer it if I edited your doc to fix these problems and ultimately get this pushed through? Or would you rather fix them yourself?

Let me know.

[M-Lipin]

Hello @Thraka sorry for the late response. I can fix the document issues. Could you please point me to the issues/requirements or sample how to fix?

@M-Lipin here are the markdownlint error messages that @Thraka was referring to. Fixing them just involves making sure there's a blank line before and after a list.

@M-Lipin I'm starting on some WinForms planning for .NET Core content. I can jump in here and fix this up for you today. Is that OK?
