Fix module cleanup workflow repo gate

The dispatch job was gated on `github.repository == 'trask/opentelemetry-java-instrumentation'`, which caused every scheduled run on the upstream repo to short-circuit: only `activation` ran, and `dispatch`/`agent`/`finalize`/`safe_outputs`/`conclusion` all completed in 0s as skipped.
