chore(changelog): retarget unreleased 1.23.2 → 1.24.0 (#951)

Retarget the staged (unreleased) `# 1.23.2` CHANGELOG section to `#
1.24.0` in both client packages, ahead of cutting the 1.24.0 beta.

#950 added new public API (`dangerously_log_query_text` config option +
per-request `span_attributes`), which is an additive **minor** release.
`1.23.2` was never published, so the section's contents — the OTEL
features (#950) and the #947 `Array(Date)` binding fix — ship together
as `1.24.0`.

Header-only change; content is unchanged. Required by the release
skill's Step 1 (the CHANGELOG must carry the exact version header before
the version bump).
