ci: Add Winget Releaser workflow

[sitiom]

This action automatically generates manifests for Winget Community Repository (microsoft/winget-pkgs) and submits them.

gdu is available in Winget () but is outdated. I have manually created a PR to update it for now (microsoft/winget-pkgs#96456), but this workflow should automatically keep it up to date for the new versions.

Before merging this:

1. Add a classic PAT with public_repo scope as a repository secret named WINGET_TOKEN.

2. Fork https://github.com/microsoft/winget-pkgs under @dundee. The action will use that fork for making a branch and creating a PR with the upstream winget-pkgs repository on every release.
3. Install Pull on the winget-pkgs fork to ensure that it is constantly updated.

You can test out the action inputs in this playground.

If you want to see an example of a PR created using this action, see microsoft/winget-pkgs/pulls (Pull request has been automatically created using 🛫 WinGet Releaser).
