Windows support

[jszwedko]

Hi all!

Thank you for creating this Github Action! We started using it with our self-hosted runners for https://github.com/vectordotdev/vector when we ran into issues with disk space.

I was just curious if you'd be open to contributions adding support for Windows? We have self-hosted Windows runners that it would be nice to use this with too.

Thank you!

I personally would not be opposed to supporting Windows for this action (the more the merrier!), but I don't think it is possible without drastically changing the way the action works unfortunately.

Running containers via normal means with GitHub Actions are only supported on Linux according to GitHub:

• https://docs.github.com/en/actions/using-workflows/workflow-syntax-for-github-actions#jobsjob_idcontainer
• https://docs.github.com/en/actions/creating-actions/creating-a-docker-container-action#introduction
• Support container operations on Windows runners actions/runner#904 (comment)

As this action is container-based (and there isn't any way of doing a "mixed" action to my knowledge), supporting Windows would require transitioning this action to be of type JavaScript or composite, both of which have other downsides.

If any of this changes in the future (or if there is some opportunity I missed), I would be happy to add (or accept a PR for) the functionality!
