fix(cli): add redis-compress flag to argocd admin dashboard command (#13055)

[aborilov]

Previously, gzip compression was disabled and not configurable, which made it impossible to work with gzipped Redis cache. This commit adds support for gzip compression to the ArgoCD admin dashboard.

Fixes: #13055
