Hoi
There are no silly questions, so don't apologize
The diffs/diff folder only contains files with every change to the files in th epackage. This is only as a refernce for those who develop and hacked their site, so they can see if they need to adjust their hacks if their hacked files are changed by the system.
In other words, you don't need to put them on the server
They're just for the developers as a reference so everyone can see what's changed in this version.
