Subject: [PATCH] feat: add riscv64 architecture support

Map Node.js 'riscv64' arch to 'riscv64gc' to match the release asset
naming convention used by wasmtime, wasm-tools, and wit-bindgen.

wasmtime v43+ ships riscv64gc-linux binaries; this allows the setup
action to install wasmtime on riscv64 runners (e.g. RISE Project
ubuntu-24.04-riscv runners).
