fix(scripts): stop double-generating CHANGELOG on release

Drop the redundant 'bun --bun run changelog:generate &&' prefix from
release scripts; bumpx already calls @stacksjs/logsmith internally
with the proper from/to tag range, so the standalone pre-step was
prepending a duplicate section to CHANGELOG.md on every release.
