New Campaign tutorials and courses - Wrong applications

Issue in ./current.md
The section New Campaign tutorials and courses lists Campaign v8 for all 10 tutorials. When in fact all but 2 are filed under Campaign v7. And the last 2 filed under Campaign Standard. I.e.:

- [Schedule messages](https://experienceleague.adobe.com/docs/campaign-standard-learn/tutorials/communication-channels/email/schedule-messages.html?lang=en)
- [Send a proof for an email delivery](https://experienceleague.adobe.com/docs/campaign-standard-learn/tutorials/communication-channels/email/sending-test-preparing-sending-email.html?lang=en)

Open ./current.md and find the “New Campaign tutorials and courses” section. Check the linked tutorials against their Adobe Campaign product paths, then update the listed applications so the entries identify Campaign v7 or Campaign Standard where appropriate; done means all 10 tutorials show the correct application.
