Add WinGet as distribution channel
Problem to solve
WinGet was used for CLI distribution when it was hosted on GitHub: https://gitlab.com/gitlab-org/cli#windows. Now we don't publish through WinGet yet.
Proposal
Build Windows installer using InnoSetup (already done in GitHub): https://github.com/profclems/glab/blob/trunk/.github/workflows/release.yml#L103-L155
Update the WinGet manifest: https://github.com/microsoft/winget-pkgs/tree/master/manifests/g/GLab/GLab
