fix(release): rename stale @objectstack/create-objectstack refs in pending changesets

changeset version hard-fails on a changeset naming a package that is not in
the workspace, and two pending changesets (better-auth-1-7-0-rc-2 batch, OSV
2026-07 batch) still said @objectstack/create-objectstack while the scaffolder
package is named create-objectstack. With the hotcrm gate now advisory in
pre-mode (#3627), this was the next and only blocker in the version step:
the v17 train died before creating its Version Packages PR.

Verified locally: changeset status reproduced the exact CI error before the
rename and assembles the release plan cleanly after it.

+Repo-plumbing only: two pending changesets referenced the scaffolder by its old `@objectstack/create-objectstack` name, which `changeset version` rejects because the workspace package is named `create-objectstack`. Renamed the entries; releases nothing by itself.
