node.js is broken on Alpine 3.12

```
/usr/bin/docker exec  b6b00889ce59b62d3fdddcf068b7ca6cd09606da324e33b7e3754c74054cb218 sh -c "cat /etc/*release | grep ^ID"
Error relocating /__e/node24_alpine/bin/node: pthread_getname_np: symbol not found
```

Upgrading both validate (was 3.19) and release (3.12) to 3.20
instead. I hope the release one was just a missed upgrade.
