The dependency on `make shell` is confusing and unnecessary since
`update-status-go.sh` script only requires availability of the
`nix-prefetch-url` utility to check SHA256 of the `status-go` verison.
Use of `make shell` with this script can also cause issues when running
`make run-android` if already in the shell, which prevents spawning a
new one and effectively stops changes to `status-go-verison.json` file
taking effect.
