Unable to verify packages within a UDS bundle during UDS deploy command

Describe the solution you'd like

• Given a UDS bundle containing signed Zarf packages
• When I attempt to deploy the UDS bundle
• Then I want feedback on whether the Zarf packages are signed with a given public key

Describe alternatives you've considered

Alternatives include running zarf package verify for each package before deploying a bundle, but this adds a bunch of unnecessary complexity
