Preview build publishing workflow in a topic PR may fail if release PR has been merged to `main` but new version has not been published yet

If you merge a release PR that bumps the version of a package that has dependents such as `@metamask/base-controller`, but you do not approve the release yet (i.e., the new version is not published), then when you open a PR and attempt to publish preview builds, the workflow will fail during the step that changes all of the workspace package names to their preview equivalent. Because of this, Yarn attempts to resolve dependencies to their published version instead of their local version, and when it does this, it isn't able to find the published version.

To fix this, we could consider overwriting all interdependencies to use the preview build versions by renaming them from `@metamask/` to `@metamask-previews/` and adjusting their versions.

Trace the preview build publishing workflow to the step that renames workspace package names, then inspect how Yarn resolves dependent workspace packages after a release PR is merged but unpublished. Reproduce the failure with that release state and verify that preview publishing resolves local preview dependencies without requiring the new published version.
