### What happened

In the UI for DAGRuns there are checkboxes that allow multiple DAGRuns to be selected.

Within the Actions menu on this same view, there is a Delete option which allows multiple DAGRuns to be deleted at the same time.

Task instance view on the UI does not offer the same option, even though Task Instances can be individually deleted with the trash can button.

### What you expected to happen

I expect that the Task Instances can also be bulk deleted, in the same way that DAGRuns can be.

### How to reproduce

Open up Task Instance and DAGRun views from the Browse tab and compare the options in the Actions dropdown menus.
