Delete this unused acquisition method:

from https://github.com/folio-org/mod-orders-storage/tree/v13.7.2/src/main/resources/data/acquisition-methods

It is not used:
https://github.com/search?q=org%3Afolio-org%20061f1375-6422-4cb4-9edf-4ccf116a5f6f&type=code
https://github.com/search?q=org%3Afolio-org+%22Test+user+method%22&type=code

This is the data install code:
https://github.com/folio-org/mod-orders-storage/blob/v13.7.2/src/main/java/org/folio/rest/impl/TenantReferenceAPI.java#L68
It installs the acquisition methods from
https://github.com/folio-org/mod-orders-storage/tree/v13.7.2/src/main/resources/data/system/acquisition-methods , not from
https://github.com/folio-org/mod-orders-storage/tree/v13.7.2/src/main/resources/data/acquisition-methods

The acquisition method is used for unit tests only, therefore it should be deleted from the generated jar file and moved to the test resource directory.
