winget: update license/copyright urls One of our winget manifests currently has hardcoded, outdated values for its LicenseUrl and CopyrightUrl fields. This is because the winget-create tool that we use to automatically generate and publish our manifests cannot change these fields. In light of this, instead of creating and submitting manifests with a single command, update the workflow to do the following: 1. Create the manifests. 2. Update the LicenseUrl and CopyrightUrl fields with the correct version. 3. Submit the manifests. Additionally, add workflow_dispatch trigger for easier testing in the future.
