chore(release): drop pending changesets to publish 0.13.0 (#1105)

main is at 0.13.0 (bumped by the #1096 release-PR merge) but 0.13.0 was never published: the verify-deps release bug (fixed in #1104) made the post-merge run open a 0.13.1 PR instead of publishing. These two changesets remained on main, keeping changesets/action on the version path. Removing them makes the next Release run take the publish path and ship the already-versioned 0.13.0 with its full changelog, tags, and GitHub releases. They are restored in the follow-up 0.13.1 PR.
