The previous code did not identify the output display correctly,
leading to wf-recorder asking the user to select the region when the
user requested the display output to be selected.
With this change the bash script will use slurp with the -o flag to
identify the display output.
This has not been tested with wl-screenrec as no change has been made to
its call signature in omarchy-cmd-screenrecord and the wl-screenrec
binary is not included in the default omarchy installation.
