Add the option to set the screenshot directory in the screenshot utility
I was just playing around with GNOME 42.3 and I was looking for the setting to change the save directory for screenshot.
I didn't find any documentation about it, so I searched the source code and it appears it is hardcoded to be "Screenshots" (or a translated version of that string). I'm used to setup my screenshot directory as "screenshots" in lowercase and I think it would be nice to have that feature.
