feat(oxide): add riscv64 (linux-gnu) prebuilt binary

Add riscv64gc-unknown-linux-gnu to the oxide release matrix so a prebuilt
@tailwindcss/oxide-linux-riscv64-gnu package is published. Cross-compiles
with gcc-riscv64-linux-gnu (napi-cross does not ship a riscv64 toolchain),
mirroring the existing aarch64 entry otherwise.
