Python version 3.12 and 3.13 do not support "ImpImporter"

The Newer version of Python do not support "ImpImporter" while making the installation. Running command "make test" will give the following error message :

register_finder(pkgutil.ImpImporter, find_on_path)
^^^^^^^^^^^^^^^^^^^
AttributeError: module 'pkgutil' has no attribute 'ImpImporter'. Did you mean: 'zipimporter'?

The newer versions has removed "ImpImporter" from its "pkgutil" module.
I would like to suggest to mention about it in the [Installation docs](https://vulnerablecode.readthedocs.io/en/latest/installation.html) to depreciate the version to 3.11 so that all the commands can run.
