fix(tududi): clear bash hash table after setup_nodejs in update

In some edge-case environments where Node.js was previously installed
via a non-standard method, bash's command hash table can cache a stale
npm location. Adding 'hash -r' after setup_nodejs clears the cache,
forcing bash to re-resolve npm from the current PATH.

Fixes #12920
