Include the dispatched profile in the concurrency group

When a Publish Snapshot Artifacts run is already in progress, the manual refresh path in update-source-input-data.yml dispatches this workflow twice back-to-back for the Russell and mega-cap profiles; with this workflow-level group both dispatched runs share the same key. GitHub’s default concurrency behavior allows only one pending run and cancels/replaces an existing pending run, so the first profile publish can be dropped before it ever runs (GitHub docs). Include inputs.profile in the group or use queue: max so both requested publishes are preserved.
