whereas `overrideCoqDerivation` allows you to override arguments to the
call to `mkCoqDerivation` in the Coq library.
Note that all Coq libraries in Nixpkgs have a `version` argument for
easily using a different version. So if all you want to do is use a
different version, and the derivation for the Coq library already has
support for the version you want, you likely only need to update the
`version` argument on the library derivation. This is done with
`.override`:
```nix
coqPackages.QuickChick.override { version = "1.4.0"; }
```
