New review comment by Piraty on void-packages repository

https://github.com/void-linux/void-packages/pull/27915#discussion_r559519102

Comment:
1. a small hint about git requirement would have made it more obvious
2. you can write `version.h` (as defined [here](https://github.com/bkaradzic/GENie/blob/44918162588e56512ddac6264b08ca6ba4e67468/scripts/release.lua#L18-L27)) on your own with the information available in the template, as well as maybe even skip running that release script entirely and mimic what does in `pre_configure()`. or just patch out the lines calling `git`, whatever you like
