A replacement bash function for the old drush launcher

drush_launch_function.sh

#!/bin/bash

#
# Drush launcher no longer works in Druapl 10 because of
# the TTY check in the new Symfony's Process implementation.
#
# This script search for a "vendor/bin/drush" in the current
# folder herichey and proxy parameters to that drush. Feels
# like old launcher behaviour.
