Follow-up to the trunk PR #4807 forward-merge for cassandra-5.0. The
trunk R1 commit (8e0700a7cb on the chain leading to 32826fe563)
rewrote reference/cql-commands/commands-toc.adoc to retarget 38
broken xref:reference/cql-commands/<page>.adoc[...] entries to the
corresponding anchors in developing/cql/{ddl,dml,functions,mvs,
security,types}.adoc, kept 6 entries that still resolve under
cassandra:reference/cql-commands/, and dropped 4 DSE-only entries
(RESTRICT, RESTRICT ROWS, UNRESTRICT, UNRESTRICT ROWS).
The same transformation is applied here to cassandra-5.0. The trunk
commit was not cherry-pickable because 5.0's commands-toc.adoc had
diverged from trunk's pre-R1 version by ~9 lines (the DSE-only
entries plus an unrelated formatting drift); a direct edit replacing
the file with trunk's post-R1 content was the cleanest application.
One trunk-only entry is omitted: LIST SUPERUSERS (target
developing/cql/security.adoc#list-superusers-statement). That anchor
does not exist on cassandra-5.0; the LIST SUPERUSERS command was
added after 5.0.
All 29 retarget anchors plus the 6 cassandra:reference/cql-commands/
target pages verified to exist on upstream/cassandra-5.0.
