[Bug]: Failing test on python 3.12: `TestCodeBlockChecker.test_check_python_returns_error_on_syntax_warning`

[sanjayankur31]

To Dos

• [X] I tested with the latest released version.

• [X] I have checked the issues and think that this is not a duplicate.

• [X] I added a very descriptive title to this issue.

Example Code (python)

While building the package on Fedora, we're seeing this one test fail.

I guess a new test case needs to be added for the new py3.12 error message.
