[GITEA] Fix cancelled migration deletion modal

- https://codeberg.org/forgejo/forgejo/pulls/1473 made that dangerous
actions such as deletion also would need to type in the owner's name.
This was apparently not reflected to the deletion modal for migrations
that failed or were cancelled.

(cherry picked from commit c38dbd6f88)
