CI: add wamr_wasi_extensions to the release assets (#4425)

you can find an example of the release asset at:
https://github.com/yamt/wasm-micro-runtime/releases/download/WAMR-2.3.999/wamr-wasi-extensions-2.3.999.zip

note: this is a static library for wasm32-wasi. no need to provide
per host OS (macOS, ubuntu, etc) binaries.
