Database: Permitted Use Cases for all data packages

[AndyDaniel1]

As #3214 is implemented we need to set the approved use cases for the already published data packages.

The use case "scientific use" should be defined for all data packages that have been published to date.

For all data packages that contain a CUF, the use case teaching purposes should also be defined.

This is still a Todo.

@AndyDaniel1 this is a bit of scripting work that needs to be performed directly on the database since we obviously can't update already released data packages directly. The steps are roughly:

• filter data packages that are flagged shadow=true
• check if there's an existing array of approved usages (many data packages don't have it)
• if so, check if SCIENTIFIC_USE is already included
• otherwise add it

Fortunately this field is not indexed in Elasticsearch. Otherwise we would have had to implement some kind of API call to make sure everything is updated correctly in both.

However we definitely need to create some test cases to make sure nothing goes wrong when executing the script in production.
