python-docs: fix override examples

Browse Source 
Use example package `zerobin` instead of `bepasty-server` which
is no longer part of python-packages.
This fixes the examples for current nixpkgs versions.

If you are using the `bepasty-server` package somewhere, for example in `systemPackages` or indirectly from `services.bepasty`, then a `nixos-rebuild switch` will rebuild the system but with the `bepasty-server` package using a different `src` attribute. This way one can modify `python` based software/libraries easily.
`pythonPackages.zerobin` is now globally overriden. All packages and also the
`zerobin` NixOS service use the new definition.
Note that `python-super` refers to the old package set and `python-self`
to the new, overridden version.
