fix_: simplify version used in go:generate

[siddarthkay]

Summary

This PR simplifies version generation.
Mobile nix derivation for status-go is unable to find this script since its filtered out via our mkfilter.
https://github.com/status-im/status-mobile/blob/develop/nix/status-go/source.nix#L31

Otherwise we get errors like :

sh: line 1: ../../_assets/scripts/version.sh: cannot execute: required file not found

@siddarthkay, I would fix the mkfilter instead of duplicating the code.
Next time you want to change it - you'll need to do it in 2 places.
I don't think it simplifies version generation.
