fix: fetch key-value store records as attachments (#573)

See apify/apify-core#25006 - fetching with `attachment=true` now allows
getting unmodified HTML, without the script snippet for disabling
cookies. There are no other side effects (except that the response will
have `Content-Disposition: attachment`, but that is irrelevant to
clients other than web browsers)
