you're looking at docs for the 'latest' development branch of ceph,
rather than a specific release. this particular feature was added for
squid:

https://docs.ceph.com/en/squid/radosgw/metrics/#user-bucket-counter-caches

and unfortunately does not exist for the reef release:

https://docs.ceph.com/en/reef/radosgw/metrics/#user-bucket-counter-caches
returns 404
