doc/rados: remove HitSet-related key information

Remove HitSet-related key information from
doc/rados/operations/pools.rst. HitSet-related keys are relevant only to
releases of Ceph that support cache tiering. Only Quincy and earlier
(inclusive) releases of Ceph support cache tiering. Backport this commit
from main to Reef, but not to Quincy or to release branches earlier than
Quincy.
