**Related issue:** Resolves: #35528 (followup)
This migration should fix `.pkg` installers that have a mismatched
software title, as well as software (versions) that are using the wrong
title. It's a little bit risky, as it could modify `software`,
`software_installers`, and `software_titles` data.
For software versions it just checks if the title's source is not the
same as the software. For installers it uses installers with
platform=`darwin` where the title's source isn't `apps`, which should
probably be the only case after the previous migration to convert titles
with source `pkg_packages` to `apps`.
Changefile was already added for 35528 in a previous PR.
