Enhance Telegram notifications with message thread support

[MrCaringi]

Add support for message threads in Telegram notifications, allowing for more organized communication. This update modifies the notification handling to include an optional message thread ID.

Thanks for the PR, there are a couple of things missing on first glance that I'll leave in review notes.

You'll also want to make sure you clone the repo locally and test the functionality and drop a screenshot of a successful test.

1. Add thread ID as a settings migration (see previous settings migrations for examples)
2. Add thread ID as a part of the Telegram form so the end-user can set the thread ID for the notification to use.

thanks a lot for your support @alexjustesen !

I have to admit I am a little lost here, I am not familiar with pulls request,
dont know if I have to do something else,

Please feel free to discard or modify it

@MrCaringi thanks for the PR but I'm going to close it out. We're planning on implementing Apprise as a core notification channel to support additional services. Release tbd but at this point anything outside of "Database", "Email" and "Webhook" are considered deprecated.
