**Backport:** https://codeberg.org/forgejo/forgejo/pulls/9074
When registering with an email account including a comment (e.g. `me@example.com (a comment here)`), the comment is removed from the email address. It was possible to include an email address in the comment to bypass the block list. For instance if registering with `me@evilcorp.com (me@example.com)` the mail would incorrectly be verified against the block list using the comment instead of `@evilcorp.com`. This is a regression introduced in Forgejo v12.
