The [WikibaseTermboxInteraction](https://meta.wikimedia.org/wiki/Schema:WikibaseTermboxInteraction) schema was created in context of T211015 and we probably want to keep it until at least the new Termbox is available on Desktop, whenever that is.
Thus we should make sure it is migrated to the new platform.
For more context see the parent ticket.
(One of?) the Grafana boards with data from this schema https://grafana.wikimedia.org/d/000000018/eventlogging-schema?orgId=1&var-schema=WikibaseTermboxInteraction
[x] 1. Pick a schema to migrate
[x] 2. Create a new task to track this schema's migration
[x] 3. Create /analytics/legacy/ schema
[x] 4. Edit-protect the metawiki Schema page at https://meta.wikimedia.org/wiki/Schema:<SchemaName>
[] 5. Manually evolve the Hive table to use new schema
[] 6. Add entry to wgEventStreams, wgEventLoggingStreamNames and wgEventLoggingSchemas in operations/mediwiki-config
[] 7. Once the legacy stream's data is fully produced through EventGate, switch to using Refine job that uses schema repo instead of meta.wm.org
[] 8. Edit the producer extension.json and set EventLoggingSchemas to the new schema URI
[] 9. Once the producer extension.json is fully deployed, edit wgEventLoggingSchemas in operations/mediawiki-config InitialiseSettings.php and remove the schema's entry.
[] 10. Mark the schema as migrated in the EventLogging Schema Migration Audit spreadsheet
