Describe the bug

I have run a test run on a machine, and I am using Telegram as notification service.

Unfortunately, It looks like the amount of docker containers that have been updated (10) was a bit too much for Telegram's message length limit, so Watchtower failed to send the report entirely.

This is the message that has been reported instead in the logs:

watchtower-1  | time="2024-11-26T01:11:47+01:00" level=error msg="Failed to send shoutrrr notification" error="Message exceeds the max length" index=0 notify=no service=telegram

Steps to reproduce

Have Watchtower update enough containers to fill the entire size of a telegram message (4096 characters)

Expected behavior

Watchtower should be able to split the message in enough parts to send the entire message to Telegram's servers.

In case of using pushover for notifications, the message seems to simply be cut off at the API limitation of 1024 4-byte UTF-8 characters, losing the rest of the notifcations entirely.

Maybe some kind of MAX_NOTIFICATION_SIZE Parameter, to split notifcations into enough calls to get the entire notification across would be an idea. I dont know how much of an undertaking to add that would be, probably not insignificant.
