2021-February-21 - Prerelease - 2.6.6@a6950ed9d4

Update bot deployment - always deploy zip file (#8890)

Instead of deploying a jar file for 'latest', instead
run 'releases' task to generate a zip file and copy that.
When not using latest, we download the zip file, by also
using a zip file in the latest case, we get similar steps
where the zip file after being copied or downloaded is
then always extracted.
