fix: remove duplicate es-toolkit@1.47.1 keys from lockfile (#4833)

PR #4831 (commitizen v4.3.2) merged from a stale base and appended
duplicate es-toolkit@1.47.1 entries to the packages and snapshots
sections. The duplicated mapping key made pnpm-lock.yaml invalid YAML,
breaking `pnpm install --frozen-lockfile` on master (ERR_PNPM_BROKEN_LOCKFILE).
