Subject: [PATCH] tantivy: add build-tantivy.yml for riscv64 wheels

Builds the tantivy 0.26.0 Python bindings (quickwit-oss/tantivy-py) for
riscv64 via cibuildwheel driving the maturin/pyo3 backend directly from
the upstream checkout, matrix cp312/cp313/cp314/cp314t. Rust toolchain is
installed in-container via rustup since the project ships no
[tool.cibuildwheel]. Tests run the upstream pytest suite plus the
doctest-modules pass over the installed wheel's compiled docstrings.
