Base Devise initializer on the latest version

We haven't updated this initializer for years, so here's the updated
version. The `expire_auth_token_on_timeout` doesn't seem to exist
anymore, and a few more options have been added.

Note that the default Devise initializer configures
`config.responder.error_status` and `config.responder.redirect_status`
so they follow Hotwire/Turbo conventions. For now, I'm commenting these
lines because we currently don't use Hotwire/Turbo.
