clickhouse-cpp: CMake 4 support and stop publishing revisions for older versions

[perseoGI]

Summary

Changes to recipe: clickhouse-cpp/2.5.1

Motivation

While compiling userver, clickhouse-cpp arises with the known CMake 4 incompatibility.
This PR aims to fix this issue by setting CMAKE_POLICY_VERSION_MINIMUM and also, remove old versions not in use by CCI.
