Alternative Logback Slack Appender - a tested and maintained library

[maximro]

Hi @maricn

We have built our own Slack Appender for Logback. It has reasonable test coverage and definitely works in 2023 and 2024.
As we use it for our projects, we are going to maintain it for the foreseeable future.

Perhaps you may put a link to our project as an alternative to yours.
