Order is not preserved on IRC <-> Telegram

[matheusfillipe]

Describe the bug
Messages relayed to telegram can arrive in a different order than on IRC. This doesn't seem to happen to other gateways.

To Reproduce

1. Create a IRC <-> Telegram gateway from the documented config.
2. The IRC server or user must have no fakelag or rate limit.
3. Messages will not arrive in order on telegram when multiple lines are sent from IRC.

Expected behavior
The order of messages should be preserved accross all targets.

Suggestion
It seems that shortest messages have a tendency of arriving first. I think this TODO is refearing to it and the sending should have a per channel lock so that it is blocked until the message is sent.

Environment (please complete the following information):

• OS: Ubuntu 24.04 LTS
• Matterbridge version: version: 1.26.1-dev d16645c from docker image 42wim/matterbridge:latest
