Handle licence expired or updated error from App Store Connect

[nid90]

There are some licenses on the App Store Connect side that, when expired, affect all API calls. Most API calls against the store start failing with the following error:

Spaceship::ProgramLicenseAgreementUpdated: A required agreement is missing or has expired. - This request requires an in-effect agreement that has not been signed or has expired.

We should handle those and show a banner to the users to update the license before they can make a release, update train settings, or take any action against the App Store.
