chore: remove test_distribution.py

It was always skipped in CI tests and relies on plugins that
do not support python 3.12.

Remove the file and move the version check to test_cmake.

 3. Create a topic named `update-to-cmake-X.Y.Z` and commit the changes.
    For example::
 
     release=3.27.8
     git switch -c update-to-cmake-$release
-    git add -u CMakeUrls.cmake docs/index.rst README.rst tests/test_distribution.py docs/update_cmake_version.rst
+    git add -u CMakeUrls.cmake docs/index.rst README.rst tests/test_cmake.py docs/update_cmake_version.rst
     git commit -m "Update to CMake $release"
 
 4. Push the topic and create a `Pull Request`.
