Suppress Cppcheck checking level

Refine the pre-commit hook to enforce a minimum Cppcheck version of
1.90, alerting users with an error message and providing guidance on
compiling Cppcheck from source if their version is outdated.

Additionally, upgrade the hook for "--check-level=exhaustive" option
against Cppcheck versions 2.11 and above, ensuring a comprehensive
analysis. This adjustment leverages the enhanced capabilities
available from version 2.11, promoting more detailed code quality
checks.

This commit is aiming for fixing commit #3aa0d55's misinformed title.
We just add comments to explain why this changes.
