Preview Store package breaks Stable

[JohnMcPMS]

Prerequisites

• Write a descriptive title.
• Make sure you are able to repro it on the latest version
• Search the existing issues.

Summary

The current preview package has added items that the stable version does not support. Presumably this is related to #1368

Expected behavior

The schema version used in the preview package allows for the new field and the stable version uses the new schema version to validate it (or uses semver and a relaxed validation scheme).

The stable version carries on in the face of one failed resource manifest.

Actual behavior

The stable version rejects the preview resource manifest and then fails to enumerate any resources.

Perhaps we need to allow the schema to allow additional properties and backport the change to 3.1 to allow for future additions not to break released versions

[SteveL-MSFT]

Discussed in WG, use unevaluatedProperties instead

[SteveL-MSFT]

This was fixed in 3.1.3
