This change uses the shacl-vue config option 'update_shapes_default' to
temporarily set the 'sh:minCount: 1' annotation on all pid property shapes.
This is because the shacl export of the latest linkml v1.11.1 excludes that
annotation. The reason that it is excluded, or more specifically whether that
reason is correct, is not fully clear to me yet. Until that becomes clear, we
can keep this custom bandaid, so that pid fields remain required in shacl-vue
forms
