[PM-26030] [Chromium importer] Add specific error when no logins were found

[djsmith85]

🎟️ Tracking

https://bitwarden.atlassian.net/browse/PM-26030

📔 Objective

When importing using the new chromium importer and the target browser does not have any logins to import, it would just show a generic error. This refines it to re-use the message we show on other importers
