Lit package archives are non-determininistic

[truemedian]

I've been looking into maintaining the AUR packages for lit, luvit and luvi. However, the zip archives obtained by downloading https://lit.luvit.io/packages/luvit/lit/v3.8.5.zip and https://lit.luvit.io/packages/luvit/luvit/v2.18.1.zip return a different zip every time they're run.

This prevents the packages from properly checksumming the archives (which is not a requirement, but would definitely be better)
