Add clj-kondo support for libpython-clj2 namespaces

- Add hook for libpython-clj2.require/import-python (v2 namespace)
- Add lint-as rules for require-python (v1 and v2)
- Add :unresolved-namespace exclusions for python.* namespaces
- Extend :unused-namespace exclusions to include python.* aliases

The existing config only covered the legacy libpython-clj namespace.
Users of libpython-clj2 were getting various warnings:
- "Unresolved namespace python" when using python.str, python.list, etc.
- "Unknown require option: :bind-ns" from require-python

Note: py., py.., py.-, py*, py** macros are now natively supported
in clj-kondo 2025.04.07+ (issue #2512) and don't need special config.

Closes #268
