License vs Copyright for manifest

[Code. (superusercode)]

Currently the application license field in the YamlCreate still includes that shows Copyright (c) Microsoft Corporation. Is it intended for a manifest to just reuse that line again for the copyright field or should Proprietary go in there instead? When updating the valve manifest (https://github.com/microsoft/winget-pkgs/blob/master/manifests/v/Valve/Steam/2.10.91.91/Valve.Steam.locale.en-US.yaml#L12-L14) I used it twice.

Before we had a Copyright or CopyrightUrl field, many packages just put the copyright in the License field. For open source projects, I like to try and find a copyright if one is available, and otherwise I use the license file URL for the LicenseUrl.
