Log worker name in steno logger

[johha]

Logging the worker name will make it easier to analyse the logs of particular worker process/thread.
The worker name will be added as an additional key in the data field where e.g. the request_id is already logged.
Example:

{"timestamp":"2025-01-14T09:51:48.249447000Z","message":"(0.001651s) (app/actions/organization_delete.rb:33:in `block (2 levels) in delete') (query_length=43) DELETE FROM \"organizations\" WHERE \"id\" = 32","log_level":"debug","source":"cc.background","data":{"worker_name":"cc_global_worker_generic thread:7","request_guid":"0728f0f0-7f96-420c-ab2d-1a3768bb7047"},"thread_id":39340,"fiber_id":39360,"process_id":68504,"file":"/Users/bommel/.rbenv/versions/3.2.6/lib/ruby/gems/3.2.0/gems/sequel-5.88.0/lib/sequel/database/logging.rb","lineno":88,"method":"public_send"}
