Describe the bug
Hi !

We have followed the instructions on how to install and configure botcube, but unfortunatly the bot is unresponsibe.

Looking at the logs, we can see a lot of not found messages

Also, is it normal that the bot is away ?

To Reproduce
Installed with Helm2

helm upgrade  helm-botkube --namespace botkube \
  --set config.communications.slack.enabled=true \
  --set config.communications.slack.channel=k8s \
  --set config.communications.slack.token=xoxb-xxxxxxxxxxxxxxxxxxxxxxx  \
  --set config.settings.clustername=abcd \
  --set config.settings.allowkubectl=false \
  --set image.repository=infracloudio/botkube \
  infracloudio/botkube

Expected behavior

Screenshots

That's a bug in documentation side. We have updated the helm3 commands but helm2 still pointing to older syntax. Let me fix it
