Remove CSR check from deploy-config

[chickenbeef]

Issue #, if available:

When trying to build the project as per the instructions in the README, the installation goes into an infinite loop waiting for a CSR.

The CSR creation was removed from 0.3.0:

Use in-cluster=false so that the webhook reloads certificates from the filesystem rather than creating CSRs to request certificates (using CSRs is now deprecated and will not work versions later than v0.3.0).

$ make cluster-up IMAGE=amazon/amazon-eks-pod-identity-webhook:latest
...
mutatingwebhookconfiguration.admissionregistration.k8s.io/pod-identity-webhook configured
until kubectl get csr -o \
		jsonpath='{.items[?(@.spec.username=="system:serviceaccount:default:pod-identity-webhook")].metadata.name}' | \
		grep -m 1 "csr-"; \
		do echo "Waiting for CSR to be created" && sleep 1 ; \
	done
Waiting for CSR to be created
....
Waiting for CSR to be created

Description of changes:

This PR updates the makefile to align with the CSR removal introduced in 0.3.0.

@chickenbeef wanna pick the other change from #150 as well?

@dims definitely, I overlooked that.

Updated the prep-config, delete-config and removed the hack/webhook-patch-ca-bundle.sh as it's no longer needed.
