fix: delete archived feature toggles in the UI (#5411)

This PR addresses 2 tasks that aim to fix and improve the UI/UX on
archived feature toggle deletion:

-
https://linear.app/unleash/issue/UNL-260/delete-feature-toggle-dialog-update-word-toggles-to-singular-toggle
-
https://linear.app/unleash/issue/UNL-282/deleting-multiple-toggles-in-the-project-archive-the-batch-selector

Essentially:

- Makes it clearer that we're deleting a single feature toggle by
changing the text to singular toggle
- Improves clarity further by adding a list of feature toggles about to
be deleted
- Fixes a bug where the batch selector would not be cleared after
deleting multiple feature toggles
