Can't select the desired dag version for a backfill dag run

Apache Airflow version

3.0.0

If "Other Airflow 2 version" selected, which one?

What happened?

I am making a bunch of edits to a dag, and I want to re-run a backfill for a specified date range. When I do, Airflow performs the backfill with the version of the dag that originally ran, and there's seemingly no way in the UI to specify that I want to re-run using the latest dag version.

What you think should happen instead?

The latest version should maybe be the default version for backfills, and users should be able to select the version that runs.

How to reproduce

1. Run a backfill over a certain date.
2. Update the dag code
3. Run a backfill over the same date from (1)
