Support for workflows in macos-latest and windows

[allanleal]

Hello. Does act support workflows running on macos-latest and windows-2019 in addition to Linux workflows?

The docker images listed in the link below do not include windows and macOS.

Ok, just found the answer.

Windows and macOS based platforms are currently unsupported and won't work (see issue #97)
