Testing

Demo recording uploaded to Slack as it doesn't fit GitHub limits: https://kubeshop.slack.com/archives/C03MRCX7UE9/p1707757327981479?thread_ts=1707493295.011349&cid=C03MRCX7UE9

Here is the config that I used for testing:

Fix #1379

CI tests are failing in the same way on main so it's not related to do PR itself: https://github.com/kubeshop/botkube/actions/runs/7870841341/job/21473234766

We need to investigate that.

Code and demo LGTM 🚀 didn't test it personally, but I'll try it out after releasing the latest main plugins 👍

What is the reason if this change?

[mszostok]

tests no have own go.mod you need to run server from tests folder and it breaks the flow as the dir is taken from the current path 🙂
