Add support for publishing minder to winget (Windows)

[rdimitrov]

The following PR updates the goreleaser configuration by adding winget which will allow us to publish to https://github.com/microsoft/winget-pkgs

Upon release, goreleaser will:

• generate the necessary yaml files describing the minder package
• create a version branch at a local fork of winget-pkgs (i.e. stacklok/winget-pkgs)
• create a PR to upstream

Manual work:

• Since we are using the free version of goreleaser, we'd have to go to https://github.com/microsoft/winget-pkgs, find the PR and tick all the checkboxes (I guess it helps with accepting the PR)

Blocking:

• Create a PAT (classic) scoped with repo: public_repo exposed via secrets.WINGET_GITHUB_TOKEN
• Fork https://github.com/microsoft/winget-pkgs under stacklok

Fixes: #1251
Fixes: #1252

This microsoft/winget-pkgs#124316 was created to test the changes in this PR.

@JAORMX - sorry for dismissing your review, but decided to disable opening a PR/publishing to winget-pkgs until we release 👍
