Use `project.IconName` instead of repeated unreadable `if-else` chains (#23538)

The project type will be changed in
https://github.com/go-gitea/gitea/pull/23353, so the old fix
https://github.com/go-gitea/gitea/pull/23325 will not work as well.

And I also found that there were some problems in the old fix....
