opencv4: properly install Python type-stubs 

Without these type stubs installed auto-completion for the `cv2` module
will not be available and diagnostics may not be accurate.
This is especially notable in a devshell using `mkShell` and `python3.withPackages`
leading to editors such as Neovim having a poor development experience.
