fix(docker): grant write permissions for npm-global directory

Adds a `chown` command to the Dockerfile to grant the `node` user
write permissions to the `/usr/local/share/npm-global` directory.
This resolves an `EACCES` permission denied error during the `npm install -g`
step in the Docker build process.
