Cannot set a private IPv4 for load balancer

[nicolaracco]

TL;DR

I'm trying to set the annotation load-balancer.hetzner.cloud/private-ipv4 to force a specific IPv4 address, but the load balancer always get the first available IP in the network.

Expected behavior

To be able to properly set a custom IPv4 address on the load balancer

Observed behavior

These are my current annotations:

load-balancer.hetzner.cloud/location: fsn1
load-balancer.hetzner.cloud/name: lb-external
load-balancer.hetzner.cloud/use-private-ip: "true"
load-balancer.hetzner.cloud/uses-proxyprotocol: "true"
load-balancer.hetzner.cloud/private-ipv4: "10.0.0.101"
load-balancer.hetzner.cloud/http-redirect-https: "false"

but the load balancer keeps being provisioned with the 10.0.0.10 IP (which is the first one available).

Minimal working example

No response

Log output

When the service annotations are updated I always see this log, but I'm not sure if it's related:

### Additional information

I already tried to delete the load balancer, then the service, to force hccm to re-provision the load balancer
