Update Slack courses to reflect updated Slack

Claudia Trapp

A recent update of Slack changes the look and where you find some things. I therefore can no longer recommend the existing Slack content, which uses the 2020 version.

Could you please ensure updating these courses is on the roadmap? 

Slack is such an important communication tool for hybrid/virtual offices, and I'd like to use Skillsoft content to inform our approach in the future.
