[Package Request]: Microsoft.AppInstaller Development / Release Candidate Builds

How can we help?

I would like help so I can submit the manifest.

Please read and ensure the following

• The installer meets the above requirements

Please provide the following information

I would like to have a package for the preview / release candidate / development builds of winget.
However I'm not sure whether Release Candidates, Development Builds and Preview builds should be split up into different packages or should be all together in one package (and what would be the correct package identifier for this case).
Can winget even upgrade itself to an unstable version?

Start by reviewing the winget-cli release page linked in the issue and the provided MSIX bundle URL, then check the repository's package-request guidance for how preview, release-candidate, and development builds are represented. Done means determining the package structure and identifier, then submitting the manifest if the request is supported.
