Map dualsense controller manually and disable Steam Input

This fixes the issue of swapped buttons and Triggers in the dualsense controller opening the pause menu The issue is caused by the SDL version used by hollow knight not recognizing the dualsense controller and mapping buttons properly. It is also not helped by steam input not disabling the native controller support when used in hollow knight. The issue cannot be fixed by simple mapping in steam input.

1. Disable Steam Input
2. Set the following as launch option

jonfk

#!/bin/bash

# abort on nonzero exitstatus
set -o errexit
# abort on unbound variable
set -o nounset
# don't hide errors within pipes
set -o pipefail
# Print each command for debugging
# set -o xtrace
