fix(ci): migrate with manual migrations (#10389)

In 0b09d9f2f5, the `--migrations-path` arguments were added to the `Seed
database` step. These only work for the `ecto.migrate` and family of
commands, and not with `ecto.seed`. This meant all of our CI has
essentially not been running the manual migrations.

Then, #10377 we fixed the env var when starting the services so that
manual migrations are run. That env var, however, only applies to
"releases", which the `elixir` service is not.

This caused the API service to try and run the missing manual migrations
upon startup, which failed because they would then be run out-of-order.

To fix all of the above, we fix the `Seed database` step of the
perf-tests job to ensure it runs all migrations. The other places where
we seed the database already handled this properly.
