Can't delete dagrun/task instance metadata from the UI

What happened?

Especially when iterating on dag changes, it is sometimes very helpful to be able to delete task instance or dag run history. In Airflow 2.x, you could delete records from the DB via the UI, but this isn't yet possible in Airflow 3.

What you think should happen instead?

Users should be able to delete dag runs and task instances from the UI.

We already have Delete Dag Run in the rest api, so that should be easy to add to the UI

The API is missing Delete Task Instance though, so we need to add that first.

It would be helpful with this https://github.com/apache/airflow/blob/main/airflow-core/src/airflow/ui/src/components/DeleteDialog.tsx for who want to try solve this~

I think I could help with TI part including API and UI
