🎉 Add OWID data managers to metadata

[Marigold]

Implements #2465

Add a field owid_data_managers to DatasetMeta. The original proposal suggested setting it in snapshot and then propagating (+combining), this PR doesn't add it to Snapshot and only uses it in the garden / grapher step. I felt that it's not as useful in snapshot metadata and would unnecessarily complicate things.

The grapher step should map managers to user ids and save them in the new JSON column in datasets table. Alternatively, we could save just manager names (since querying on JSON fields is painful anyway).
