Subject: Tell users how to assign a $EDITOR.

In case there's no $EDITOR assigned users would see a cryptic:

```
% EDITOR= bin/rails secrets:edit
Waiting for secrets file to be saved. Abort with Ctrl-C.
sh: /var/folders/wd/xnncwqp96rj0v1y2nms64mq80000gn/T/secrets.yml.enc: Permission denied
New secrets encrypted and saved.
```

That error is misleading, so give a hint in this easily detectable case.

Fixes #28143.
