IIRC this used to be necessary, but I can't for the life of me remember why, I will respond again if I can think of it 😆

@EItanya
Thanks for the response!

During the CI testing, 1 CI has failed.

Error: 2 errors occurred:
	* clusterrolebindings.rbac.authorization.k8s.io "kagent-getter-rolebinding" already exists
	* clusterrolebindings.rbac.authorization.k8s.io "kagent-writer-rolebinding" already exists


make: *** [Makefile:327: helm-install-provider] Error 1
Error: Process completed with exit code 2.

I investigated the CI logs and I found that both kagent chart and kagent-tools chart are creating same clusterrolebindings.

Reference: https://github.com/kagent-dev/tools/blob/main/helm/kagent-tools/templates/clusterrolebinding.yaml

So that I added this commit for this conflict.

May I ask for this to be checked as well? Thanks.
