Automatic releases to WinGet require manual setup for first released version

[WojciechMazur]

During the Scala 3.6.2 release publishing to WinGet failed - https://github.com/scala/scala3/actions/runs/12258732279/job/34199187420

The used action requires at least previously released version in https://github.com/microsoft/winget-pkgs that would work as a template for a new release.
We need to setup a first manifest for Scala 3.6.2 and ensure that our fork https://github.com/dottybot/winget-pkgs/ would be able to sucessfully make automatic updates (eg. ensure that Microsoft CLA check would be signed)

The PR adding Scala CLI can be used as a template: microsoft/winget-pkgs#110242
