Automation must work with Windows

[nicolas-lang]

part of this is possible using git-hub actions like

• https://github.com/Roang-zero1/factorio-create-release-action (bash)
• https://github.com/nicolas-lang/factorio-create-release-action (python)

Check https://github.com/nicolas-lang/factorio.InserterCranes for a working example:

• A Tagged push creates a release which is auto-uploaded to the mod portal.
