tree-wide: convert rust with git deps to importCargoLock

 such as the one in the example above. `cargoHash` should instead be
 used for [SRI](https://www.w3.org/TR/SRI/) hashes. For example:
 
+Exception: If the application has cargo `git` dependencies, the `cargoHash`/`cargoSha256`
+approach will not work, and you will need to copy the `Cargo.lock` file of the application
+to nixpkgs and continue with the next section for specifying the options of the`cargoLock`
+section.
