Can't disable toast for modal action responses

- Laravel Version: 11.0.0
- Nova Version: 4.35.10
- PHP Version: 8.2

### Description:

Is there any way to disable a toast for modal action responses? Looking at the code it appears as though there isn't, but showing a toast is redundant when you're opening a modal.

It's confusing to say that an action has succeeded when the interaction has not concluded

I have verified that the same behavior exists in v5

### Detailed steps to reproduce the issue on a fresh Nova installation:
Create a modal action
Run the action
"The action was executed successfully" is toasted, and cannot be prevented with a manual falsey value in the data array.

The issue does not name files or tests. Reproduce the behavior on a fresh Nova installation with a modal action, then trace how the modal action response triggers the success toast; done means the toast can be disabled for modal responses without suppressing the modal interaction.
