add windows suport

[insinfo]

I have swift 5.9 and swiftformat 0.52.7 installed but when I use the format option in VS Code it deletes all source code

Thanks for the report! As I don't have access to a windows system, I am unable to reproduce your problem.

As debugging windows issues requires lots of ping pong with a tester, I would appreciate a pull request by any volunteer.

Still a bug. It deletes all the source code when trying to autoformat on save.

[vknabel]

Correct. I haven’t done anything, because as mentioned, I don’t have access to a device running windows.

I would appreciate a pull request by any volunteer.

Alternatively I could simply disable all formatting on windows.

Take a look at vknabel/vscode-apple-swift-format#40 (comment)
same fix works for swiftformat too
