feat: add support for Python 3.12 when determining what's in the stdlib (#143)

* fix(stdlibs): fallback to last item - i.e 'last' known Python version - in stdlibs if no match

* fix(stdlib): add 3.12 stdlib with removed modules + fix missing 3.11 modules that should have been there

* fix(test internals): check for existing dist with dash and with package name using underscore

* fix: bump lock files

* bump version to 1.12.2
