Describe the bug

Configuring Infiscal Kubernetes authentication with Client JWT as Reviewer JWT Token is not working because external-secrets service account doesn't have the system:auth-delegator permission

To Reproduce
Steps to reproduce the behavior:

1. Install ESO
2. Configure a SecretStore using Infisical and kubernetesAuthCredentials
3. Configure Infisical Kubernetes Auth to use Client JWT as Reviewer JWT Token (leave the Token Reviewer JWT field empty)

Expected behavior
ESO needs to authenticate correctly against Infiscial using Kubernetes Auth and Client JWT as Reviewer JWT Token
