Update Catalog.getAllPageDicts to always propagate the actual Errors (PR 14335 follow-up)

Rather than "swallowing" the actual Errors, when data fetching fails, ensure that they're always being propagated as intended to the call-site instead.
Note that we purposely handle `XRefEntryException` specially, to make it possible to fallback to indexing all XRef objects.
