Make target toolchains and manylinux versions more explicit, then add a riscv64 manylinux build for fast-walk targeting manylinux 2_39 specifically. This requires enabling RISE RISC-V Runners as a GitHub app for the project. More info here: https://riscv-runners.riseproject.dev/

I've performed a test run on my fork: threexc#1

This is being done on behalf of RISE, using the Python Wheels Dashboard to track upstream support for the Python ecosystem.

Distinguish between 'target' (the Rust toolchain for the architecture)
and 'arch' (the shorthand for it) in the build matrix, since not all
architectures (e.g. ppc64le, riscv64) use the same pattern. Also be
explicit about the manylinux version in the 'linux' job, since it also
varies by platform. Since the musllinux job always uses 1_2, we don't
need to include it there.

Thanks for this! .github/workflows/CI.yml is generated by maturin (maturin generate-ci github), and we don't hand-edit it. Could you upstream these CI changes to maturin's CI generator (PyO3/maturin, src/ci/) and open a new PR there? Once maturin ships it, we'll regenerate and pick it up.
