ci(windows): add winget releaser workflow

[sitiom]

What does this PR do?

• Closes Support winget to download Bun #8116

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

Note

Only merge until the following PRs are resolved. The action only works when at least 1 version of the package already exists in winget-pkgs:

• New package: Oven-sh.Bun version 1.1.0 microsoft/winget-pkgs#147222
• New package: Oven-sh.Bun.Baseline version 1.1.0 microsoft/winget-pkgs#147226

Before merging this:

1. I'm assuming ROBOBUN_TOKEN already has the public_repo scope to make commits.
2. Fork https://github.com/microsoft/winget-pkgs under @oven-sh. 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.

• Documentation or TypeScript types (it's okay to leave the rest blank in this case)
• Code changes
