This doesn't really explain anything. If you need to have types for this package, you just need to have @types/jest-image-snapshot installed. This is something that should be explained by the package itself

jest-image-snapshot users need to use expect.extend, which unfortunately doesn't add typing. However, going over their docs again, there is a section mentioning the necessity to add a matcher. I will close the PR as the package docs (partially) explain how to do it.
