cleanup: delete migration-data

Deletes the `migration-data` package from the `packages`
directory. This package is no longer useful and will exist
in a previous commit/fork of the repo. It will be very painful
to maintain the ability to run the migration indefinitely
into the future, it should be safe to assume that users
that want to perform the migration can check out the legacy
commit and run it from that point.
