edit link on public document detail site doesn't work properly because of Turbo

[rlskoeser]

Describe the bug
Clicking the edit link on the document details page of the public site doesn't load the admin page properly.

To reproduce
Steps to reproduce the behavior:

1. Log in to the backend with an account that has document edit permission
2. Go to the public document details page
3. Click the edit link
4. See a blank public site page (header/footer but no content)
5. If you reload the page, you'll see the admin edit page correctly.

Expected behavior
You should see the edit page for that document in the admin without having to reload.

Additional context
This is a Turbo problem — Turbo is trying to load the link in the current turbo frame, and we need to tell it not to.
