Description

The configure_background function couldn't correctly detect existing Pictures directory and installed the nord-background repo to the top level of the Pictures directory

https://github.com/ChrisTitusTech/linutil/issues/303

Testing

Tested both having no Pictures directory and an existing Pictures directory, then ran the DWM-Titus script from the TUI. Both times the images from the nord-background repository wound up in ~/Pictures/background

Impact

N/A

Issue related to PR

• Resolves #303

Additional Information

This will still fail if you already have a ~/Pictures/nord-background folder that's not empty but that seemed a bit extra to go clobbering that if it existed.
