The show_contact_by_external_id method in the Python SDK raises a generic ApiError for 404 responses instead of the expected NotFoundError.

This is inconsistent with other methods in the same SDK - for example, companies.attach_contact and companies.detach_contact both correctly raise NotFoundError on 404.

ForbiddenError, is probably also affected

see intercom/contacts/raw_client.py -> show_contact_by_external_id i.e. ~1072 line
