Hide file from git diff output

git diff will show patches for text files, but not for binary files, like images, because the output is not likely to make any sense. Some checked in text files, like package-lock.json, can be considered binary too: while technically composed of text characters, it's opaque to a human reader. In addition to that, it's diff output long, and commonly fills the entire screen when running git diff. To avoid this, we can mark the file as binary by unsetting the diff attribute in .gitattributes:

package-lock.json -diff
