fix: Append to condition misleading message (frappe#17696) (frappe#17709

)

* Update Append to doctype description

Hello,

To append email to a doctype to enable automatic creation, there are two required fields listed
![image](https://user-images.githubusercontent.com/109596710/182173486-d7141ec9-451d-4de9-8303-a8e8dbd289bf.png)

However, there is a third one required which is lacking in the above description (as seen below), because the email settings of the document must be enabled.

I propose to simply modify the sentence to the following :

Append as communication against this DocType (must have fields ("Status", "Subject") and "Sender" defined in the related doctype Email Settings).

To avoid any problem, in the code, it becomes the following :
Append as communication against this DocType (must have fields (\"Status\", \"Subject\") and \"Sender\" defined in the related doctype Email Settings).

The same must be applied in email_domain.json and in lots of csv in translations of course.
