fix(utilities): add globalfields.json to readGlobalFieldSchemas ignore list

Prevents silent data corruption when a CLI v1 export archive containing
global_fields/globalfields.json is passed to readGlobalFieldSchemas — the
bulk array file is now skipped instead of being parsed as a single schema
element. readContentTypeSchemas is unaffected.
