Update template for polaris tool due to upstream change

Upstream changed their release naming convention at some point.
Old assets were polaris_linux_amd64.tar.gz. New assets are
polaris_10.2.0_linux_amd64.tar.gz. The template in tools.go
hadn't been updated to match, so every request hit a 404.

Unit and e2e tests now pass.

Fix for argocd's massive CRDs

These didn't work properly some of the time - they exceed
256k lines (apparently) so better to apply first via
server-side kubectl.
