Implement migration notebook for `v10.3.0` to `v10.4.0`

[eecavanna]

Description

In this branch, I created a Python notebook that can be used to migrate a Mongo database from conforming to schema v10.3.0 to conforming to schema version v10.4.0. That migrator was introduced into the nmdc-schema repo "late" (i.e. in v10.5.4).

Fixes #556

I am bypassing branch protection here in order to merge this migration notebook in. This is currently the norm for migration notebooks.
