Contributor-name-type is required for contributor added to POL

Purpose:

Currently we've hardcoded the contributor-name-type to name: "Personal name" which is present in the inventory reference data (see MODORDERS-204). However, there's no guarantee that the reference data will be loaded/used by all tenants. As a result, we need to allow the tenant to specify which contributor-name-type they want to use when creating instances upon order placement.

Approach

contributor.json has 2 properties: contributor (any string) which is used by UI and contributorType (UUID of the type record) which is not in use. The MODORDERS-247 renames contributorType to contributorNameTypeId and makes it required.
The existing contributor name types can be fetched from inventory-storage by calling GET /contributor-name-types

User "Personal Name" by default. If it doesn't exist, use the first from the list of contributorNameTypes. If no contributorNameTypes exist, fail the request. This is consistent with other "lookups" in mod-gobi.
