Fix DownloadFunc when migrating releases (#27887) (#27890)

Browse source 
Backport #27887 by @Zettat123

We should not use `asset.ID` in DownloadFunc because DownloadFunc is a
closure.

1bf5527eac/services/migrations/gitea_downloader.go (L284-L295)

A similar bug when migrating from GitHub has been fixed in #14703. This
PR fixes the bug when migrating from Gitea and GitLab.
