Batch modal action not working

[maciazek]

When I tried to create batch modal action (for deleting) I encountered problems. I created reproducer table in demo app (Experimental -> Batch modal action), action is named "delete employees". Also started working on fix and prepared separate branch for testing in demo app. I found that batch modal action was using Stimulus' URL value, but identifiers were not appended to it. In my fix I replaced it with 'href' attribute, which is used in other batch actions.

What do you think @Kreyu - is this the right way to fix this?
