update cmake

[k-ido]

This pull request updates CI workflows and modernizes CMake configuration across the project to improve compatibility and maintainability. The changes focus on updating build environments, refining CMake policies and minimum version requirements, and cleaning up legacy code in CMake files.

CI Workflow Updates:

• Updated the runner for documentation deployment to use ubuntu-latest instead of the older ubuntu-20.04 in .github/workflows/deploy_docs.yml.
• Simplified the OS matrix for the main workflow by replacing specific Ubuntu versions with ubuntu-latest and removing ubuntu-22.04 and ubuntu-20.04 from .github/workflows/main.yml.

CMake Modernization and Cleanup:

• Set the CMake minimum required version to 3.5...3.10 and introduced CMAKE_POLICY_VERSION_MINIMUM 3.10 in the top-level CMakeLists.txt to ensure compatibility with newer CMake features.
• Removed legacy cmake_minimum_required(VERSION 2.8.0 ) lines from all submodule CMakeLists.txt files (src/ComplexUHF/CMakeLists.txt, src/ltl2inv/CMakeLists.txt, src/mVMC/CMakeLists.txt, src/pfupdates/CMakeLists.txt, tool/CMakeLists.txt) for consistency and to avoid redundant version checks.

Python Test Configuration:

• Added a CMake policy setting (CMP0148) to suppress warnings about the deprecated PythonInterp package in test/python/CMakeLists.txt, with a note to migrate to find_package(Python3 REQUIRED) in the future.
