Description of the problem:

When a TempoStack is created on a OCP cluster with only IPV6 networking stack, the compactor and ingestor pods run in CrashLoopBackOff with the following errors.

Version of components:

opentelemetry-operator.v0.74.0-5

tempo-operator.v0.1.0-6

OCP Server Version: 4.14.0-0.nightly-2023-05-31-080250

Cluster profile: https://gitlab.cee.redhat.com/aosqe/flexy-templates/-/blob/master/functionality-testing/aos-4_14/upi-on-baremetal/versioned-installer-packet-single_stack-http_proxy

How Reproducible:

Always

Steps to reproduce the issue:

*Deploy a OCP cluster with IPV6 single networking stack.

*Install the Distributed Tracing data collection and Tempo Operator.

*Create a minio instance with the following config.
