Extend the Issue links API to include creation and update times
The Delivery team needs access to the creation/update times of issue links through the API, as mentioned in gitlab-com/gl-infra/delivery#1250 (closed). This data is currently not exposed through the API, but is stored in the database. The following fields should be exposed per issue link:
created_at
updated_at
This is likely just a matter of changing API::Entities::IssueLink
to expose these two fields, and extending any tests that need extending. A feature flag is probably overkill for such a simple change.
