docs: Would like official documention on producing a Windows installer with Shorebird

This has come up 3 times in the last week. Once via email and two via issues: https://github.com/shorebirdtech/shorebird/issues/3190 https://github.com/shorebirdtech/shorebird/issues/3201 Users would like official docs as to how to create a windows installer with Shorebird. This work isn't currently planned, but I'm filing this in case someone would like to write a doc, we'd be happy to publish it. e.g. https://docs.shorebird.dev/code-push/guides/development-workflow/ https://github.com/shorebirdtech/docs
