[PATCH proxmox-backup] docs: notifications: fix broken calendar match examples

[Arthur Bied-Charreton <a.bied-charreton@proxmox.com>]

The calendar matcher examples showed weekday ranges as start-end. The
correct syntax is start..end - these example configs do not parse.

Update the examples to the correct a..b range syntax.
