--export-client-list option doesn't work when IPv6 addresses are returned

[edward-milkey]

Describe the problem
First, thanks for the great work here!

When --export-client-list option is enabled, redis_connected_clients_details metrics are not provided by the exporter as expected when Redis CLIENT INFO returns IPv6 addresses. This is when using v6.0.14 of Redis.

I encounter IPv6 addresses returned from CLIENT INFO when using Azure Redis Cache service with private endpoints.

What version of redis_exporter are you running?
v1.55.0

Running the exporter
What's the full command you're using to run the exporter? (please remove passwords and other sensitive data)
--redis.addr rediss://MY_REDIS:6380 --redis.password "REDACTED" --debug --export-client-list --export-client-port

Expected behavior
What metrics are missing? What metrics are wrong? Is something missing that was present in an earlier version?

The exporter returns other metrics, but the client list metrics (redis_connected_clients_details) are not present.
