`kubelb docs` command make it compatible with hugo

[ahmedwaleedmalik]

We would like to copy, as it is, the generated docs to our official documentation at https://docs.kubermatic.com/kubelb/latest/cli/references. Although this is not possible atm since the generated docs are not compatible with Hugo.

IMO instead of changing the command which works for everyone. We should script this out. The missing pieces are:

1. Page headers are missing

+++
title = "kubelb loadbalancer get"
date = 2025-08-27T00:00:00+01:00
weight = 80
+++

2. The anchor tags are wrong

* [kubelb loadbalancer](kubelb_loadbalancer)  - Manage KubeLB load balancers

Instead of

* [kubelb loadbalancer](.../kubelb_loadbalancer)  - Manage KubeLB load balancers
