Add copy command for windows

[AbhinavOmprakash]

This will pretty much add support for windows.

I tried lein uberjar and I could use shh as indicated. Creating, changing, and deleting a password work.

The only hitch is you have to run it with.
java -jar target/shh.jar
for some reason the snapshot.jar doesn't work but shh.jar does.

Although I think this hitch can be solved by creating an installer script for windows, what do you think?

I almost forgot about graalvm. 🤦🏻‍♂️
I currently don't have it on my machine. But since the jar works on windows, I suppose the native image would work too.

Until a GitHub workflow is setup we can rely on the jar, and install that instead.

I already have a Windows build set-up actually, if you check in the repo .github/workflows directory and in the _test.yml file, so with this merge I can run the windows build and you should get a nice .exe.
