Each of the templates need to be updated to use ndjson formatted files, since legacy json format is going away https://gitlab.com/gitlab-org/gitlab/-/issues/232633 ### Proposed solution Update instance template with new ndjson format. This will ensure once https://gitlab.com/gitlab-org/gitlab/-/issues/232633 is done and legacy format is removed, it won't break instance templates. It can be done by: 1. Creating a new project via instance level template 2. Exporting created project, this will generate new archive using ndjson 3. Replacing existing template @ `vendor/project_templates` with a new one There are 25 templates to update, so it might be better to do this transition in batches, processing 5 templates per MR.
