fix(ci): Reorder build steps to prevent lockfile inconsistency

Reorders the steps in the 'publish-bundle' job to run the bundle creation and size check *before* modifying the package.json files for release.

This prevents the 'package-lock.json' from becoming out-of-sync, which was causing the 'npm ci' command in the bundle size action to fail.
