publish:package task fails when multiple zarf-package-*.tar.zst files exist

[marshall007]

Modifications needed to be made in defenseunicorns/uds-package-mattermost#99 to handle the case where multiple packages are being built/published in the same project. In other words, you should be able to call create:package multiple times and then have some way to call publish:package for each package that is built (or once for all of them?).

For example:

  - name: publish-packages
    description: Build packages
    actions:
      - task: create:package # creates `zarf-package-mattermost-amd64-9.9.1-uds.0.tar.zst`
      - task: create:package # creates `zarf-package-mattermost-plugins-amd64-9.9.1-uds.0.tar.zst`
        with:
          path: ./plugins
          options: "--flavor ''"
      - task: publish:package # publishes all packages named `zarf-package-mattermost-*.tar.zst`
        with:
          filter: mattermost-*
