The README.md file provides instructions for deploying the controller (https://github.com/kubernetes-sigs/secrets-store-sync-controller?tab=readme-ov-file#deploy-the-controller). However, there are discrepancies between the instructions and the actual outcomes of the commands.

Specifically, when executing the command: VERSION=e2e make docker-build
The resulting Docker image is named controller:e2e instead of secrets-store-sync-controller:e2e as stated in the documentation.
This inconsistency between the documentation and the actual behavior may lead to confusion for users attempting to deploy the controller.

 ## Troubleshooting
