refactor(cpp): improve CLionWorkspaceContextProvider logic

The CLionWorkspaceContextProvider logic was refactored to improve readability and maintainability. The code now checks for the existence of the CMakeLists.txt file before proceeding. Additionally, the code now uses a single if statement to check for the presence of "gtest" or "gmock" in the text, and another if statement to check for the presence of "catch" or "Catch". These changes make the code more concise and efficient.
