adapter.py --version output should have two words

[wingo]

pywasm automatic test runs have been failing for a few days: https://github.com/WebAssembly/wasi-testsuite/actions/runs/17195593573/job/48777073184

This is because wasi-testsuite expects the output of calling adapter.py --version to be something like "pywasm 1.2.3.43.45.5.5" whereas since the last version update, --version now just prints the version part.
