[Installation] Provide AIBrix upgrade support and guidance

[Jeffwan]

🚀 Feature Description and Motivation

I received feedback that users are encountering issues where the aibrix-controller-manager cannot list resources of type "mutatingwebhookconfiguration" from the master branch. After following up with the users, it appears that they updated the image directly instead of uninstalling and reinstalling the manifest from the beginning.

We need to provide upgrade guidance to users so that they can perform the upgrade correctly. There are some dependencies that need to be addressed, such as better support for kubectl apply or Helm.

Use Case

The feature allows users to upgrade AIBix easily
