This commit removes the Apache copyright note from the Cassandra Stress page.
It's a follow up to https://github.com/scylladb/scylladb/pull/21723, which missed
that update (see https://github.com/scylladb/scylladb/pull/21723#discussion_r1944357143).
Cassandra Stress is a separate tool with separate repo with the docs, so the copyright
information on the page is incorrect.
Fixes https://github.com/scylladb/scylladb/issues/23240
Closes scylladb/scylladb#24219
(cherry picked from commit d303edbc39)
Closes scylladb/scylladb#24256
