Replace DeleteModal with Confirmation Modal

[edmundito]

What / How

This replaces the Delete Modal component with the Confirmation Modal component as they both do the exact same thing. It also ensures that when delete is confirmed it navigates away from the page and to connection / source / destination list page.

Recommended reading order

Start with DeleteBlock, then read from top to bottom.

Awesome! I think this resolves this issue I put in yesterday. Was there an existing issue for this part of the deletion workflow that I didn't see?

A general note: I think data-id should be data-testid in all places. It seems we're not specifically using data-id for any logic, but just to later find that element better (in testing?), in which case we should try to stick to data-testid, which is the name of the parameter that testing-library as well as cypress are expecting.

@timroes there are a few places where data-id is being used, I was adding support to what was already there. I'd like to spin this off into its own issue to do a full cleanup instead.

@tealjulia What I did is very basic and I think it does deserve more work separately such as adding a notification. At least for now it will band-aid the confusion that even though it was deleted, the page is still there.
