[pve-devel] [PATCH docs] notification mode: revise subchapter

[Alexander Zeidler]

- Display the values and descriptions as a table.

`auto`:
- Rephrase the description so that the focus is on the recommended
  "notification-system" mode. This also fixes the incorrectly duplicated
  "if no email address is entered".
- Emphasize "Send email to".

`legacy-sendmail`:
- s/version/versions/
- Move/Append info about future removal of this mode.

 Notification Mode
 -----------------
 A backup job configuration has the `notification-mode`
-option which can have one of three values.
-
-* `auto`: Use the `legacy-sendmail` mode if no email address is entered in the
-  `mailto`/`Send email to` field. If no email address is entered,
-  the `notification-system` mode is used.
-
-* `legacy-sendmail`: Send notification emails via the system's `sendmail` command.
-  The notification system will be bypassed and any configured
-  targets/matchers will be ignored.
-  This mode is equivalent to the notification behavior for version before
-  {pve} 8.1 .
-
-* `notification-system`: Use the new, flexible notification system.
