Example code: remove --no-interaction from Composer commands

All Composer commands used in CI should use `--no-interaction` to prevent them hanging in case interaction is expected. However, as setupPHP sets the `COMPOSER_NO_INTERACTION` flag (as of this version), this is not needed when using setupPHP.

This removes redundant `--no-interaction` arguments from the example code.
