chore: sync ConformityCredential data model with Jargon
Created by: un-cefact-github-app[bot]
Change ConformityAttestation.scope from the custom ConformityAssessmentScheme defined here (and incorrectly inheriting from Standard) to use the core ConformityScheme. See https://github.com/uncefact/spec-untp/issues/377#issuecomment-2948182003 Update to core working (where the name and description of ConformityScheme are omitted from the context). Re-save after core update. Resave after core update. Resave after allow additional properties in core.
