python3-pydantic: Enable test_docs.py

We now have Rust 1.71+ version in oe-core so we can build ruff,
add it to the ptest runtime dependencies, install docs and fix
paths in test_docs.py.

There is a known jemallocator issue on aarch64 that affects ruff
and some of the pydantic tests from test_docs.py:

E           <jemalloc>: Unsupported system page size                                                                                                       E           memory allocation of 4 bytes failed
