Update all retention policies of all project

[s4ndalHat]

Hello everyone,

Recently, we migrated our harbor instances across different cluster, and after migration, all scheduled retention policies stopped wotking..

I've looked at some issue on the repo, and the workaround is to force update the schedule of retention policies from the Harbor UI.
However, having almost 100 projects, it's plenty of manual operations to do, so I'm asking if there is an easy way to do it.

Harbor version: 2.0.2 installed by helm chart
Kubernetes version: 1.26.3

Thank you
