 * There were a bunch of changes made to the dataverse python module
   to get it working with the upgraded OSF. Then we ignored
   them. Avenge this injustice!

 * Rerunning `poetry lock` pulled in a new major version of indirect
   dep `django-datetime-field`. Pin the old version, b/c that seems
   like it could be break-y.

 * Update OSF version declare in pyproject.toml

 * Regenerate lockfile. Please setuptools, don't hurt 'em!

 * Update repository-based deps (those that pull from github.com) to
   use commitShas instead of branch names. Update in both
   pyproject.toml (for poetry) and *requirements.txt (for legacy
   installs).

 * Update metrics reports to import `elasticsearch6_dsl` instead of
   `elasticsearch_dsl`. `django-elasticsearch-metrics` was updated to
   use the ESv6-pinned version of elasticsearch_dsl. Our code was
   using the `InnerDocs` class from the v8 version of es_dsl and
   expecting it to work with the v6 version of ALL THE OTHER CLASSES
   in es_dsl. Stop doing that!

 * Fun fact: sometimes making a big dumb error will succeed
   incorrectly instead of throwing an error. Existence is a burden.

 * BTW this makes the admin metrics report return *all* the data, not
   just *some* of the data.

 * Merge in develop, which includes changes from the python 3.12
